MPLS ping and traceroute for segment routing

MPLS ping and traceroute are supported for segment routing (SR) for protocols ISIS and OSPF over IPv4. MPLS ping and traceroute also supports static SR paths using NIL Forwarding Equivalence Class (FEC) as defined in LSP ping RFCs (RFC 4379 or FC 8029). This feature also supports ECMP traceroute for protocols ISIS and OSPF and static SR paths. MPLS ping and traceroute for segment routing supports IPv4 IGP-Prefix segment FEC validation. FEC validation for IGP-Adjacency Segment ID is not supported.
