11 Basic IP routing commands The term "interface" in the routing features collectively refers to Layer 3 interfaces, including VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2 LAN Switching Configuration Guide). address-family ipv4 Use address-family ipv4 to create a RIB IPv4 address family and enter RIB IPv4 address family view. Use undo address-family ipv4 to remove a RIB IPv4 address family and all configurations in the view. address-family ipv4 undo address-family ipv4 No RIB IPv4 address family is created. RIB view # Create a RIB IPv4 address family and enter RIB IPv4 address family view. [Sysname] rib [Sysname-rib] address-family ipv4 [Sysname-rib-ipv4] display ecmp mode Use display ecmp mode to display the ECMP mode. display ecmp mode Any view network-operator # Display the ECMP mode. 1

19 standby chassis chassis-number slot slot-number: Displays backup information about routes for a card on an IRF member device. The chassis-number argument specifies the ID of the IRF member device. The slot-number argument specifies the slot number of the card. Without this option, the command displays information about routes. (In IRF mode.) Executing the command with different parameters yields different outputs: display ip routing-table ip-address: The system ANDs the entered destination IP address with the subnet mask in each active route entry. The system ANDs the destination IP address in each active route entry with its own subnet mask. If the two operations yield the same result for an entry, the entry is displayed. display ip routing-table ip-address mask: The system ANDs the entered destination IP address with the entered subnet mask. The system ANDs the destination IP address in each active route entry with the entered subnet mask. If the two operations yield the same result for an entry with a subnet mask not greater than the entered subnet mask, the entry is displayed. display ip routing-table ip-address longer-match: The system ANDs the entered destination IP address with the subnet mask in each active route entry. The system ANDs the destination IP address in each active route entry with its own subnet mask. If the two operations yield the same result for multiple entries, the entry with the longest mask length is displayed. display ip routing-table ip-address mask longer-match: The system ANDs the entered destination IP address with the entered subnet mask. The system ANDs the destination IP address in each active route entry with the entered subnet mask. If the two operations yield the same result for multiple entries with a mask not greater than the entered subnet mask, the entry with the longest mask length is displayed. display ip routing-table ip-address1 to ip-address2: The system displays active route entries with destinations in the range of ip-address1/32 to ip-address2/32. # Display brief information about the routes to the destination IP address <Sysname> display ip routing-table Summary Count : 3 Destination/Mask Proto Pre Cost NextHop Interface /8 Static NULL /16 Static NULL /24 Static NULL0 # Display brief information about the routes to the destination IP address and mask length 20. 9

Without this option, the command displays routing information for the public network. prefix-list-name: Specifies an IP prefix list by its name, a case-sensitive string of 1 to 63 characters. verbose: Displays detailed information about all routes permitted by the IP prefix list. Without this keyword, the command displays brief information about active routes permitted by the IP prefix list. standby slot slot-number: Displays backup routes permitted by the IP prefix list for a card. Without this option, the command displays routes permitted by the IP prefix list. (In standalone mode.) standby chassis chassis-number slot slot-number: Displays backup routes permitted by the IP prefix list for a card on an IRF member device. The chassis-number argument specifies the ID of the IRF member device. The slot-number argument specifies the slot number of the card. Without this option, the command displays routes permitted by the IP prefix list. (In IRF mode.) If the specified IP prefix list does not exist, the command displays information about all routes. # Create an IP prefix list named test to permit the route /24.
