Configure Multiprotocol BGP to Carry IPv6 Traffic

The family inet6 statement can be specified on a per-neighbor, per-group, or global basis. The statement allows BGP to carry IPv6 traffic.

At the appropriate global, group, or neighbor hierarchy level in BGP (shown below), configure the family inet6 statement with the labeled-unicast parameter and the explicit-null option. These additional parameters enable the IPv4 MPLS label to be removed at the destination PE router. The remaining label-less IPv6 packet can then be forwarded to the connected IPv6 network.
