## Enable IPv6

This example enables IPv6 support in the `VLAN 11` interface and assigns IPv6 addresses to `VLAN 11`.

See IPv6 Example Topology Interface and Host Addresses for the topology used for this sample configuration.

1. Enter Global Configuration mode and Interface Configuration mode in SEFOS1.

       SEFOS# configure terminal
       SEFOS# interface vlan 11

2. Enable IPv6 support in the `VLAN 11` interface.

   The command used in this example automatically configures an IPv6 link-local address on the interface and enables the interface for IPv6 processing.

       SEFOS(config-if)# ipv6 enable

3. View the automatically configured link-local address and the operational status of the interface in Privileged EXEC mode.

       SEFOS# show ipv6 interface

       vlan11 is up, line protocol is up
           Link local address:
               ffe80::214:4fff:fe6c:628f
           Global unicast address(es):
               Not Configured.
           Joined group address(es):
               ff02::1
               ff02::2
               ff02::1:ff00:3
               ff02::1:ff6c:628f
           MTU is 9216
           ICMP redirects are enabled
           ND DAD is enabled, Number of DAD attempts: 1
           ND router advertisement is disabled

4. Configure the IPv6 address in the `VLAN 11` interface.

   The type of address can be `link-local`, `unicast`, `anycast`, or `eui64`.

   Type one of these:

       SEFOS(config-if)# ipv6 address fec0::1111:0:1/96 unicast

       SEFOS(config-if)# ipv6 address fec0::1111:0:1 96 unicast

5. View the automatically configured link-local address and the unicast address configured in the previous step in SEFOS1.

       SEFOS# show ipv6 interface

       vlan11 is up, line protocol is up
           Link local address:
               ffe80::214:4fff:fe6c:628f
           Global unicast address(es):
               fec0::1111:0:1/96
