Description

In an MPLS VPN Core network, enable BGP Prefix-Independent Convergence (PIC) Edge to install a VPN route in the forwarding table for use as an alternate path when a provider edge (PE) router fails or connectivity to a PE router is lost. This alternate link is used until global convergence through the interior gateway protocol (IGP) occurs. Both OSPF with LDP or RSVP, and IS-IS with LDP or RSVP are supported.
