Usage guidelines
In an inter-AS VPN Option C network, you must execute the peer label-route-capability command in BGP
IPv4 unicast address family view/BGP-VPN IPv4 unicast address family view to enable the local router
and the peer to assign labels to BGP IPv4 routes and exchange the labeled routes for establishing the
inter-AS public network LSPs.
In a 6PE network, you must execute the peer label-route-capability command in BGP IPv6 unicast
address family view to enable the local router and the peer to assign labels to BGP IPv6 routes and
exchange the labeled routes for forwarding IPv6 packets over an IPv4 network.
