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
