MPLS transit route installation as primary MPLS fast reroute (FRR) for BGP labeled unicast prefixes

When a peer autonomous system (AS) boundary router or a link fails, traffic traversing through an inter-AS link can be rerouted provided a loop-free path is available. In networks with node protection enabled, MPLS transit routes are installed as primary backup paths for BGP labeled unicast prefixes learned from external BGP multihop sessions. This feature facilitates quicker route resolution and BGP convergence for BGP labeled unicast prefixes. To enable node protection in an inter-AS environment for BGP labeled unicast prefixes, include the protection configuration statement at the [edit protocols bgp family] hierarchy level in enhanced-ip network-services mode
