1 Chapter 13 RIP Commands NOTE: This chapter contains information about IPv4 RIP commands only. For information about IPv6 RIP commands, see IPv6 RIP Commands on page default-metric Defines the global default-metric value that will be assigned to all external routes imported into RIP for redistribution. RIP must be active on the Routing Switch for this command to be operational. To assign a default metric of 4 to all routes imported as RIP, enter the following: ProCurveRS(config-rip-router)# def 4 Syntax: default-metric <value> Possible values: 1 15 Default value: 1 deny redistribute Defines the route types upon which you do not want to perform RIP redistribution. RIP must be active on the Routing Switch for this command to be operational. RIP is enabled by default. To deny redistribution on all types of routes to the network, enter the following: ProCurveRS(config-rip-router)# deny redistribute 2 all address Syntax: [no] permit deny redistribute <filter-num> all bgp ospf static address <ip-addr> <ip-mask> [match-metric <value> set-metric <value>] The <filter-num> specifies the redistribution filter ID. The software uses the filters in ascending numerical order. Thus, if filter 1 denies a route from being redistributed, the software does not redistribute that route even if a filter with a higher ID permits redistribution of the route. The all parameter applies redistribution to all route types. The bgp parameter applies redistribution to BGP4 routes only. The ospf parameter applies redistribution to OSPF routes only. June

2 Command Line Interface Reference for ProCurve 9300/9400 Series Routing Switches The static parameter applies redistribution to IP static routes only. The address <ip-addr> <ip-mask> parameters apply redistribution to the specified network and sub-net address. Use 0 to specify any. For example, means any x.x sub-net. However, to specify any sub-net (all sub-nets match the filter), enter address The match-metric <value> parameter applies the redistribution filter only to those routes with the specified metric value; possible values are from The set-metric <value> parameter sets the RIP metric value that will be applied to those routes imported into RIP. end Moves activity to the privileged EXEC level from any level of the CLI except the user EXEC level. To move to the privileged level, enter the following from any level of the CLI. ProCurveRS(config-rip-router)# end ProCurveRS# Syntax: end exit Moves activity up one level from the current level. In this case, activity will be moved to the global level. ProCurveRS(config-rip-router)# exit ProCurveRS(config)# Syntax: exit filter Defines which IP network numbers the Routing Switch will learn from the RIP protocol and store in its IP routing table. Once RIP filters are defined, you can assign these filters to individual interfaces with the filter-group command at the Interface Level of CLI. To define a RIP filter, you must first enable RIP on the Routing Switch using the router rip command to access the RIP Router Level of the CLI. NOTE: A filter defines for inbound routes what routes it will permit to be stored in its IP routing table. For outbound routes, the filter defines what routes are allowed to be advertised through a given interface. You can also specify all routes by using the value, any, instead of specifying a specific route. An IP address and mask define a route. To define filters with respect to network traffic from , , and , enter the following: ProCurveRS(config-rip-router)# filter 1 permit ProCurveRS(config-rip-router)# filter 2 permit ProCurveRS(config-rip-router)# filter 3 permit ProCurveRS(config-rip-router)# filter 4 deny June 2005

3 RIP Commands To enable logging on filter 1 and apply the filter to interface 1/2: ProCurveRS(config-rip-router)# filter 1 deny any any log ProCurveRS(config-rip-router)# int e 1/2 ProCurveRS(config-if-e1000-1/2)# ip rip filter-group in 1 ProCurveRS(config-if-e1000-1/2)# ip rip filter-group out 1 Syntax: filter <filter-num> permit deny <source-ip-addr> any <source-ip-mask> any [log] When the RIP filter causes packets to be denied, the following messages appear in the syslog: 00d00h00m00s:W:rip filter list 1 in V1 denied , 1 packets 00d00h00m00s:W:rip filter list 1 out V1 denied , 1 packets The format of the syslog message is as follows: <time>:w:rip filter list <list-num> <direction> V1 V2 denied <ip-addr>, <num> packets The <list-num> is the ID of the filter list. The <direction> indicates whether the filter was applied to incoming packets or outgoing packets. The value can be one of the following: in out The V1 or V2 value specifies the RIP version (RIPv1 or RIPv2). The <ip-addr> indicates the network number in the denied updates. The <num> indicates how many packets matching the values above were dropped during the five-minute interval represented by the log entry. Possible values: Filter ID: 1 64 filter-group Assigns a group of defined RIP filters on either a global or interface basis. Assignments to interfaces are done at the interface level of the CLI. ProCurveRS(config-rip-router)# filter-group out Syntax: filter-group in out <1-64> [<1-64] Possible values: 1 64 (filter index value) ipv6 router rip Enables IPv6 RIP globally on an HP device that supports IPv6. To enable IPv6 RIP, you must enable it globally on the HP device and also on individual interfaces. For information about enabling IPv6 RIP on individual interfaces, see ipv6 router rip on page After you enter the ipv6 router rip command, the HP device enters the IPv6 RIP configuration level, where you can access several commands that allow you to configure IPv6 RIP. For information about these commands, see IPv6 RIP Commands on page NOTE: Enabling IPv6 RIP globally on the HP device does not enable it on individual router interfaces. To disable IPv6 RIP globally, use the no form of this command. ProCurveRS(config-rip-router)#ipv6 router rip June

4 Command Line Interface Reference for ProCurve 9300/9400 Series Routing Switches ProCurveRS(config-ripng-router)# Syntax: [no] ipv6 router rip Default value: IPv6 RIP is disabled. learn-default This feature allows a Routing Switch to learn and advertise default RIP routes. This command can be applied on a global or interface basis. This example shows the feature enabled at the global level. ProCurveRS(config-rip-router)# learn-default Syntax: learn-default neighbor Specifies those routers from which a Routing Switch will receive RIP routes. In the example below, no RIP routes will be learned from any neighbor router. By default, RIP routes will be learned from all neighbors. To configure a Routing Switch so that no RIP routes are learned from its neighbor routers, enter the following: ProCurveRS(config-rip-router)# neighbor 1 deny any Syntax: neighbor <number> permit deny <ip-addr> any Possible values: 1 64 no Disables other commands. To disable a command, place the word no before the command. offset-list Configures a RIP offset list. A RIP offset list allows you to add to the metric of specific inbound or outbound routes learned or advertised by RIP. RIP offset lists provide a simple method for adding to the cost of specific routes and therefore biasing the Routing Switch s route selection away from those routes. An offset list consists of the following parameters: An ACL that specifies the routes to which to add the metric. The direction: In applies to routes the Routing Switch learns from RIP neighbors. Out applies to routes the Routing Switch is advertising to its RIP neighbors. The type and number of a specific port to which the offset list applies (optional). The software adds the offset value to the routing metric (cost) of the routes that match the ACL. If a route matches both a global offset list and an interface-based offset list, the interface-based offset list takes precedence. The interface-based offset list s metric is added to the route in this case. You can configure up to 24 global RIP offset lists and up to 24 RIP offset lists on each interface. To configure a global RIP offset list, enter commands such as the following: ProCurveRS(config)# access-list 21 deny June 2005

5 RIP Commands ProCurveRS(config)# access-list 21 permit any ProCurveRS(config)# router rip ProCurveRS(config-rip-router)# offset-list 21 out 10 The commands in this example configure a standard ACL. The ACL matches on all IP networks except x.x. When the Routing Switch advertises a route that matches ACL 21, the offset list adds 10 to the route s metric. Syntax: [no] <acl-number-or-name> in out offset [ethernet <portnum>] In the following example, the Routing Switch uses ACL 21 to add 10 to the metric of routes received on Ethernet port 2/1. ProCurveRS(config-rip-router)# offset-list 21 in ethernet 2/1 Possible values: See above Default value: None permit redistribute Allows you to define the route types upon which you want to perform RIP redistribution. To allow (permit) redistribution of all routes received from network , enter the following: ProCurveRS(config-rip-router)# permit redistribute 1 all address Syntax: [no] permit deny redistribute <filter-num> all bgp ospf static address <ip-addr> <ip-mask> [match-metric <value> set-metric <value>] The <filter-num> specifies the redistribution filter ID. The software uses the filters in ascending numerical order. Thus, if filter 1 denies a route from being redistributed, the software does not redistribute that route even if a filter with a higher ID permits redistribution of the route. The all parameter applies redistribution to all route types. The bgp parameter applies redistribution to BGP4 routes only. The ospf parameter applies redistribution to OSPF routes only. The static parameter applies redistribution to IP static routes only. The address <ip-addr> <ip-mask> parameters apply redistribution to the specified network and sub-net address. Use 0 to specify any. For example, means any x.x sub-net. However, to specify any sub-net (all sub-nets match the filter), enter address The match-metric <value> parameter applies the redistribution filter only to those routes with the specified metric value; possible values are from The set-metric <value> parameter sets the RIP metric value that will be applied to those routes imported into RIP. poison-local routes The poison-local-routes command prevents routing loops on the ProCurve 9408sl by advertising local RIP routes with a cost of 16 ("infinite" or "unreachable") when these routes go down. ProCurveRS(config-rip-router)# poison-local-routes Syntax: [no]poison-local-routes Default value: disabled June

6 Command Line Interface Reference for ProCurve 9300/9400 Series Routing Switches poison-reverse NOTE: This command applies to the ProCurve 9408sl only. Assigns a cost of 16 ( infinite or unreachable ) to a route before advertising it on the same interface as the one on which the router learned the route. ProCurveRS(config)# router rip ProCurveRS(config-rip-router)# poison-reverse Syntax: poison-reverse Default value: Disabled prefix-list Applies an IP prefix list on the ProCurve 9408sl. An IP prefix list specifies a list of networks. When you apply an IP prefix list, the ProCurve 9408sl sends and receives only those routes whose destination is in the IP prefix list. The software interprets the prefix lists in order, beginning with the lowest sequence number. ProCurveRS(config)# ip prefix-list Routesfor20 permit /24 ProCurveRS(config)# router rip ProCurveRS(config-rip-router)# prefix-list Routesfor20 out These commands configure an IP prefix list named Routesfor20, which permits routes to network /24. The Routing Switch sends routes that go to x.x because the IP prefix list explicitly permits these routes to be sent to neighbors. Syntax: prefix-list <name> in out Possible values: The <name> parameter is the prefix list name. Specify in to filter incoming routes, or out to filter outgoing routes. quit Returns you from any level of the CLI to the User EXEC mode. ProCurveRS(config-rip-router)# quit ProCurveRS> Syntax: quit redistribution Enables RIP route redistribution on a Routing Switch. When enabled, RIP will import external routes (OSPF or Static Routes) into the RIP domain. Do this prior to setting up the redistribution table using the permit and deny commands. On the ProCurve 9408sl, you can define the routes to distribute from the IP route table into RIP routes. For example, you can specify the type of routes to redistribute and assign a metric value that will be applied to the routes imported into RIP June 2005

7 RIP Commands To enable RIP redistribution on the Routing Switch, enter the following within the Router RIP Level. ProCurveRS(config-rip-router)# redistribution To redistribute OSPF routes on the ProCurve 9408sl, and restrict the redistribution to those routes that are in the specified route-map, enter the following command: ProCurveRS(config-rip-router)# redistribution ospf route-map test Syntax: redistribution bgp connected ospf static metric <value> route-map <name> NOTE: The following options apply to the ProCurve 9408sl only. bgp applies redistribution to BGP4 routes. connected applies redistribution to directly-connected routes. ospf applies redistribution to OSPF routes. static applies redistribution to static routes. metric <value> is the metric value. The default is 1. route-map <name> is a valid route-map name. Possible values: see above Default value: disabled show Displays a variety of configuration and statistical information about the device. See Show Commands on page timers Sets the time interval for four RIP timers on the ProCurve 9408sl (see Applicable Values). RIP must be enabled and active on the Routing Switch for this command to be operational. NOTE: To set the time interval on devices other than the ProCurve 9408sl, use the update-time command. ProCurveRS(config-rip-router)# timers These commands set the update timer to 20, the timeout timer to 80, the holddown timer to 80, and the garbagecollect timer to 60. Syntax: timers <update timer value> <timeout timer value> <holddown timer value> <garbage-collect timer value> Possible values: <update timer value> is the time interval that will exist between the transmission of regular RIP response packets. The value can be between seconds. The default is 30 seconds. <timeout timer value> is the time interval that the HP device waits for a route update. If the device does not receive an update within the timeout timer value, the given route is marked "down" and the metric is set to infinity. The value can be between seconds. The default is 180 seconds. <holddown timer value> is the time interval that the HP device waits before updating the down route with a route learned from another peer. The value can be between seconds. The default is 180 seconds. <garbage-collect timer> is the time interval after which a down route is deleted from the RIP route table. The value can be between seconds. The default is 120 seconds. Default value: See above June

8 Command Line Interface Reference for ProCurve 9300/9400 Series Routing Switches update-time Sets the time interval that will exist between the transmission of regular RIP response packets. This parameter is set to 30 seconds by default. RIP must be enabled and active on the Routing Switch for this command to be operational. NOTE: To set the time interval on the ProCurve 9408sl, use the timers command. To modify the default update time value to 120 seconds, enter the following: ProCurveRS(config-rip-router)# update 120 Syntax: update-time <value> Possible values: 1 1,000 seconds Default value: 30 seconds use-vrrp-path Prevents Backup VRRP routers or VSRP switches from advertising route information for the backed up interface, by enabling suppression of the advertisements. To suppress RIP advertisements for a backed up interface, enter the following command on the VRRP or VSRP Backup: ProCurveRS(config-rip-router)# use-vrrp-path Syntax: use-vrrp-path write memory Saves the running configuration into the startup-config file. ProCurveRS(config-rip-router)# wr mem Syntax: write memory write terminal Displays the running configuration of the HP device on the terminal screen. NOTE: This command is equivalent to the show running-config command. ProCurveRS(config-rip-router)# wr term Syntax: write terminal 13-8 June 2005
