Defining Static IPv6 Source Bindings

You can manually enter valid IPv6 addresses in the binding database.

Note that because static IPv6 source bindings consume system resources, you should avoid unnecessary bindings.

Enter the ipv6 source binding command followed by a valid IPv6 address and the interface number. Entering the VLAN number is optional.
```
device(config)# ipv6 source binding 10::10 ethernet 1/1/1 vlan 10
```
If you enter a VLAN number, the binding applies to that VLAN only. If you do not enter a VLAN number, the static binding applies to all VLANs associated with the port.

The following example configures IPSGv6 bindings on selective ports of a VLAN.

device# configure terminal
device(config)# ipv6 source binding 10::10 ethernet 1/1/1 vlan 10

The following example disables IPSGv6 bindings for an Ethernet interface.

device# configure terminal
device(config)# no ipv6 source binding 10::10 ethernet 1/1/1
