Description

Sends an MPLS echo request packet to the specified IP or IPv6 address or, alternatively, sends MPLS echo packets to the egress node in a point-to-multipoint LSP. There is no no version.

The MPLS echo request packets and echo reply packets created by this command use the LDP IPv4 LSP sub-TLV described in RFC 4379—Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures (February 2006).

The MPLS echo request packets and echo reply packets created by this command to detect connectivity to egress nodes in point-to-multipoint LSPs use the P2MP Responder Identifier TLV described in the IETF draft, Detecting Data Plane Failures in Point-to-Multipoint Multiprotocol Label Switching (MPLS) - Extensions to LSP Ping—draft-ietf-mpls-p2mp-lsp-ping-08.txt (February 2010 expiration).
