If the specified IPv6 address is a global IPv6 address it must belong to one of

static on-link prefixes defined in the interface. When a static on-link prefix is

deleted all static entries in the IPv6 neighbor discovery cache corresponding

the prefix is deleted to.
If an entry for the specified IPv6 address already exists in the neighbor

discovery cache, learned through the IPv6 neighbor discovery process, the

entry is automatically converted to a static entry.
Static entries in the IPv6 neighbor discovery cache are not modified by the

neighbor discovery process.
Use the no ipv6 neighbor

ipv6-address

interface-id

command to remove the

one given static entry on the given interface. The command does not remove

the entry from the cache, if it is a dynamic entry, learned from the IPv6

neighbor discovery process.
Use the no ipv6 neighbor

interface-id

command to delete the all static

entries on the given interface.
Use the no ipv6 neighbor command to remove the all static entries on all

interfaces.
Use the show ipv6 neighbors command to view static entries in the IPv6

neighbor discovery cache. A static entry in the IPv6 neighbor discovery cache

can have one of the following states:

• NCMP (Incomplete)—The interface for this entry is down.
• REACH (Reachable)—The interface for this entry is up.

Note. Reachability detection is not applied to static entries in the IPv6

neighbor discovery cache; therefore, the descriptions for the INCMP and

REACH states are different for dynamic and static cache entries.

Example

Example 1. The following example configures a static entry in the IPv6

neighbor discovery cache for a neighbor with the IPv6 address

2001:0DB8::45A and link-layer address 0002.7D1A.9472 on VLAN 1:

console(config)# ipv6 neighbor 2001:0DB8::45A vlan1

0002.7D1A.9472
