Much like IPv4 addresses are bound to MAC hardware addresses in the ARP table, IPv6 addresses are bound to MAC hardware addresses in the neighbor discovery cache.
Use the ipv6 neighbor command in global configuration mode to statically bind an IPv6 address to a MAC hardware address.
The following example configures a static neighbor cache entry for IPv6 address 2001:11ac:fd34:3333:0:0:0:3 on a hardware device with a MAC address of 1111.1111.1111 on interface VLAN 51:
