Configuring Multiprotocol BGP to Carry IPv6 Traffic

At the [family inet6] hierarchy level in BGP, configure the labeled-unicast statement with the explicit-null option. As with regular BGP configuration, the family statement can be specified on a per-neighbor, per-group, or global basis, so it can be configured at the following hierarchy levels:

[edit protocols bgp]
[edit protocols bgp group group-name]
[edit protocols bgp group group-name neighbor neighbor-name]
[edit logical-systems logical-system-name protocols bgp]
[edit logical-systems logical-system-name protocols bgp group group-name]
[edit logical-systems logical-system-name protocols bgp group group-name neighbor neighbor-name]

Configuring these statements enables 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 IPv6 network.

Include the labeled-unicast statement as follows:



family inet6 {


labeled-unicast {
explicit-null;
}


}
