A static entry in the ND cache causes a neighbor to be reachable at all
times
About this task
If a neighbor cannot be reached by means of Neighbor Discovery (ND), you can add a
static entry to the ND cache. A static IPv6 ND entry is like a static IPv4 ARP
entry.
device(config-if-eth-3/5)# ipv6 neighbor 2001:db8:2678::2 0000.002b.8641
Procedure
-
Access global configuration mode.
device# configuration terminal
-
Access interface configuration mode.
device (config)# interface ethernet 3/5
-
Add a static entry for a neighbor.
This example adds a static entry for a neighbor with IPv6 address
2001:db8:2678::2 and link-layer address
0000.002b.8641, reachable through interface ethernet
3/5.
device(config-if-eth-3/5)# ipv6 neighbor 2001:db8:2678::2 0000.002b.8641
