Remove IPv6 Addresses From an Interface

1. Enter Interface Configuration mode for the VLAN 1 interface.

   SEFOS# configure terminal
   SEFOS(config)# interface vlan 1
   

2. Delete the IPv6 address configured for that interface.

   SEFOS(config-if)# no ipv6 address fec0::1111:0:1 96
   SEFOS(config-if)# no ipv6 address fe80::203:2ff:fe03:501 link-local
   SEFOS(config-if)# exit
   SEFOS(config)# exit
   

3. Review the IPv6 information for the VLAN 1 interface.

   SEFOS# show ipv6 interface vlan 1
    
   vlan1 is up, line protocol is up
       IPv6 is Enabled
       Link local address:
           fe80::214:4fff:fe6c:560f
   ...
   

   The link-local address is auto-configured when you remove a link-local address in the IPv6 interface.
