Configuring Multiprotocol BGP to Carry IPv6 Traffic

You can specify the family inet6 statement 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 IPv6 packet without a label can then be forwarded to the connected IPv6 network.
