ipv6
Enables an IPv6 instance on a router that does not already have an explicit IPv6 address. Normally, performing any IPv6 configuration automatically enables IPv6 on the interface. The no version disables IPv6 on the router.
NOTE: Disabling IPv6 on the router disables all IPv6 unicast routing protocols.
