NOTE: Use this attribute to start a BGP instance corresponding to either a
specific address family in a default VRF or an IPv4 address family in a non-
default VRF.
ipv6 unicast Enter the keyword ipv6 followed by the keyword unicast to enable BGPv6
mode.
vrf vrf-name (Optional) Enter the keyword vrf followed by the name of the VRF to install the
IPv6 route in that VRF.
NOTE: It will not be possible to enable VRF mode for IPv6 unicast without

automatically delete the IPv6 VRF configurations as well.
Defaults Not configured.
