MPLS LSP Ping
The following figure shows MPLS LSP ping echo request and echo reply paths.

Configuration Examples
This example shows how to use MPLS LSP ping to test the connectivity of an IPv4 LDP LSP. The destination
is specified as a Label Distribution Protocol (LDP) IPv4 prefix and Forwarding Equivalence Class (FEC) type
is specified as generic.
RP/0/RP0/CPU0:router# ping mpls ipv4 4.4.4.4/32 fec-type generic
Wed Nov 25 03:36:33.143 UTC
Sending 5, 100-byte MPLS Echos to 4.4.4.4/32,
timeout is 2 seconds, send interval is 0 msec:
Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
'L' - labeled output interface, 'B' - unlabeled output interface,
'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
'M' - malformed request, 'm' - unsupported tlvs, 'N' - no rx label,
'P' - no rx intf label prot, 'p' - premature termination of LSP,
'R' - transit router, 'I' - unknown upstream index,
'X' - unknown return code, 'x' - return code 0
Type escape sequence to abort.
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/2/3 ms
This example shows how to use MPLS LSP ping to test the connectivity when the destination is specified as
a MPLS traffic engineering (TE) tunnel.
RP/0/RP0/CPU0:router# ping mpls traffic-eng tunnel-te 4003 source 3.3.3.3
Tue Nov 24 20:39:39.179 PST
Sending 5, 100-byte MPLS Echos to tunnel-te4003,
timeout is 2 seconds, send interval is 0 msec:
Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
'L' - labeled output interface, 'B' - unlabeled output interface,
'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
'M' - malformed request, 'm' - unsupported tlvs, 'N' - no rx label,
'P' - no rx intf label prot, 'p' - premature termination of LSP,
'R' - transit router, 'I' - unknown upstream index,
'X' - unknown return code, 'x' - return code 0
Type escape sequence to abort.
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 3/3/4 ms
This example shows how to use the show mpls oam command to display the MPLS OAM information
RP/0/RP0/CPU0:router# show mpls oam counters packet
