Description (partial)

In a single stage forwarding platform such as the NCS5500 Series,
When transferring MPLS to IP ARP unresolved path from IngressLC to EgressLC, some information is lost and the internal preroute is incorrectly performed and dropped.

This issue occurs only when IngressLC and EgressLC are different, and it occurs when ARP resolution is not done even once after LC activation.
