Egress peer engineering - Dynamic labels management and local protection for BGP-LU

You can enable traffic engineering of service traffic, such as MPLS LSP traffic between autonomous systems (ASs), using BGP labeled unicast for optimum utilization of the advertised egress routes. You can specify one or more backup devices for the primary egress AS boundary router, Junos OS installs the backup path in addition to the primary path in the MPLS forwarding table, which enables MPLS fast reroute (FRR) when the primary link fails.
