35 IP Route Table 4-6. DHCP/BOOTP Parameters Mode IP Address The method by which the DHCP relay chooses an IP address to include in the DHCP request. When relaying a DHCP/BOOTP request, the relay has to write its own IP address into the relayed DHCP request. This address is used by the DHCP server to determine the subnet from which the client s IP address has been allocated. When the router has multiple IP addresses on the same VLAN, any of these addresses can be used when relaying DHCP requests. The Mode field controls the behavior of the DHCP relay, in choosing the IP address to write into the DHCP request. Possible modes are: Default - The router chooses one of the addresses itself. The address chosen will be the lowest IP address on that VLAN. Specific - The router is configured with a single IP address to be used with all relayed requests arriving on the VLAN. This address must be one of the router s IP addresses on the specified VLAN. It must be entered in the IP Address field. Duplicate - The router duplicates each request arriving on the VLAN, and sends multiple copies of the request to the DHCP server - one copy for each of the router s IP addresses on the VLAN. One of the router s IP addresses on the VLAN. This is used for all relayed requests, if Mode is set to Specific. You can create, modify, or delete DHCP/BOOTP parameters.

38 Chapter 4 Table 4-8. RIP Interface Parameters RIP Version Interface Cost Default Route Metric Accept Default Split Horizon Authentication Type The router can be configured to operate either RIP version 1 or RIP version 2 on each IP interface. The configuration of the RIP version must be consistent on each subnet. That is, all routers should be configured with the same RIP version on their interface to the subnet. When possible, homogeneous configuration of the RIP version in the network is recommended. RIP1 - The router runs regular RIP on that interface, following the RIP version 1 subnet aggregation rules. That is, it advertises an aggregate route for the net as opposed to advertising subnet routes across the network boundary. RIP2 - The router runs RIP version 2 on that interface. RIP version 2 advertisements are sent as multicast rather than broadcast. No route aggregation is done in RIP version 2. RIP version 2 allows for Variable Length Subnets Masks (VLSM), meaning that subnets of the same net may have masks of different lengths, and may be of different sizes. The cost of using this interface. RIP chooses the route with the lowest total cost (metric) for each destination. The metric of the default route entry in RIP updates originated on this interface, if configured to "Default Route Only". Whether to accept default route entries in RIP messages received from other routes on this interface. The method for handling routes learned from this interface, when sending updates to this interface.

50 Chapter 4 Access Control Table The device provides sophisticated hardware-based access control packet filtering of forwarded IP traffic. The user can specify whether to forward, block, or block and report packets of specific types by configuration of access control statements. IP access control statements can specify source and destination IP address ranges, as well as the application type. The IP address ranges are defined by an IP address and mask (wild-card), and can specify a single IP station, a subnet or net, or all IP stations. An example of a simple access control statement would be that IP stations of the net can not communicate to station More advanced access control statements can specify the protocol above IP (e.g. TCP, UDP) and specific applications (UDP/TCP port numbers), e.g. HTTP or Telnet. The device will check the TCP/UDP destination port against configured applications. The access control filtering rules can be asymmetric, allowing certain traffic in one direction while blocking the same application in the opposite direction, based on which side initiates the session. In order to allow a certain application, when the default is block, the access control statements must explicitly allow for both the packets in one direction (e.g. requests) and the packets in the other direction (e.g. replies). Packets in the first direction usually have the application s well-known port number in the TCP destination port, but the replies usually use dynamic port numbers in the destination port. For that purpose, all replies can be allowed in that direction by configuring an access control statement in the device with port number >1023. This statement means "forward all the packets, from these source addresses to those destination addresses, whose destination port number is above 1023". When the TCP port >1023, the device will also check that the TCP ACK bit is set. This additional check protects against attacks via protocols using high-number ports, by guaranteeing that the packet is not an initiation of a new session - the packet is part of an established session that was previously initiated from the other direction and allowed by the device. 44 Avaya M-MLS Routing Manager User Guide

The mask defining a range of addresses by setting how many bits of the destination address are relevant. Select the protocol (All, ICMP, UDP, TCP) to filter. This field applies if the Protocol is UP or TCP. The user can select one of the predefined ports or add a user-defined value by typing its number. Only 10 user-defined ports are allowed. Avaya M-MLS Routing Manager User Guide 45

52 Chapter 4 Table Access Control Table Window Operation Whether the indicated traffic is allowed access or not: Forward - Traffic is allowed access. Block - Traffic is not allowed access. Block and Report - Traffic is not allowed access, and an SNMP trap is sent containing the source address of the traffic and the Entry ID. You can create or delete entries in the Access Control table.
