Disabling IPv6 on a VLAN

While one IPv6-enabling command is configured on a VLAN, IPv6 remains enabled on that VLAN. In this case, removing the only IPv6-enabling command from the configuration disables IPv6 operation on the VLAN. That is, to disable IPv6 on a VLAN, the following commands must be removed from the VLAN configuration:
  • ipv6 enable
  • ipv6 address dhcp full [rapid-commit]
  • ipv6 address autoconfig
  • ipv6 address fe80::<interface-id> link-local
  • ipv6 address <prefix>:<interface-id>

If any of the above remain enabled, IPv6 remains enabled on the VLAN and, at a minimum, a link-local unicast address is present.
