Enhanced egress protection in Layer 3 VPNs

Enhanced point-of-local-repair (PLR functionality is available, in which the PLR reroutes service traffic during an egress failure. As part of this enhancement, the PLR router no longer needs to be directly connected to the protector router. Previously, if the PLR was not directly connected to the protector router, the loop-free alternate route could not find the backup path to the protector. A new configuration statement, advertise-mode, enables you to set the method for the interior gateway protocol (IGP) to advertise egress protection availability.
