Table 51: TLVs Supported by MPLS LSP ping (continued)
Comments Value Type Number
This TLV is included in the MPLS echo request
packet to validate whether the IP address
specified in the TLV is an IP address of one of the
interfaces in the router. Four sub-TLVs are defined
for inclusion in the P2MP Responder Identifier TLV
in the echo request message. P2MP Responder Identifier 11
This TLV is included in the LSP ping message
(echo request) to enable the egress node of a
point-to-multipoint LSP to delay the transmission
of the response by a time interval that is limited
by the value specified in this TLV. In JunosE
Software, the delay is set to a maximum of 30
seconds. Echo Jitter 12

MPLS Connectivity Verification and Troubleshooting Methods
In IP networks, the ping and traceroute commands enable you to verify network
connectivity and find broken links or loops. In MPLS-enabled networks, you can use the
ping command to determine whether IP connectivity exists to a destination even when
the ping packets must traverse multiple LSPs. You can use the traceroute command to
determine the labels that data packets use when traversing LSPs to the destination.
