ip neighbor

Summary/usage

ip neighbor [del] <intfc> <ip-address> <mac-address> [static] [no-fib-entry] [count <count>] [fib-id <fib-id>] [proxy <lo-addr> - <hi-addr>].

Declaration and implementation

Declaration: ip_neighbor_command2 (src/vnet/ip-neighbor/ip_neighbor.c line 816)

Implementation: ip_neighbor_cmd.

set ip neighbor

Summary/usage

set ip neighbor [del] <intfc> <ip-address> <mac-address> [static] [no-fib-entry] [count <count>] [fib-id <fib-id>] [proxy <lo-addr> - <hi-addr>].

Description

Add or delete IPv4 ARP cache entries.

Note
&#39;set ip neighbor&#39; options (e.g. delete, static, &#39;fib-id <id>&#39;, &#39;count <number>&#39;, &#39;interface ip4_addr mac_addr&#39;) can be added in any order and combination.
Example usage

Add or delete IPv4 ARP cache entries as follows. MAC Address can be in either aa:bb:cc:dd:ee:ff format or aabb.ccdd.eeff format. 

vpp# set ip neighbor GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe

vpp# set ip neighbor delete GigabitEthernet2/0/0 6.0.0.3 de:ad:be:ef:ba:be

To add or delete an IPv4 ARP cache entry to or from a specific fib table: 

vpp# set ip neighbor fib-id 1 GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe

vpp# set ip neighbor fib-id 1 delete GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe

Add or delete IPv4 static ARP cache entries as follows: 

vpp# set ip neighbor static GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe

vpp# set ip neighbor static delete GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe

For testing / debugging purposes, the &#39;set ip neighbor&#39; command can add or delete multiple entries. Supply the &#39;count N&#39; parameter: 

vpp# set ip neighbor count 10 GigabitEthernet2/0/0 6.0.0.3 dead.beef.babe
