ping mpls
Use this command to check the connectivity between ingress and egress of LSP. This command uses MPLS echo request and reply messages, similar to Internet Control Message Protocol (ICMP) echo request and reply messages, to validate an LSP.
Segment routing ping is an extension of the MPLS LSP ping to perform connectivity verification on the segment routing control plane. Use this command to check connectivity if an LSP traverses entirely through a segment routing domain.
You can initiate the segment routing ping operation only when the segment routing control plane is available at the originator.

Applicability
This command was introduced in OcNOS version 4.0.
Example
#ping mpls ospf-sr ipv4 10.0.1.33/32 destination 127.1.0.1 flags detail
Sending 5 MPLS Echos to 2.32.0.0, timeout is 5 seconds
Codes:
'!' - Success, 'Q' - request not sent, '.' - timeout,
'x' - Retcode 0, 'M' - Malformed Request, 'm' - Errored TLV,
'N' - LBL Mapping Err, 'D' - DS Mismatch,
'U' - Unknown Interface, 'R' - Transit (LBL Switched),
'B' - IP Forwarded, 'F' No FEC Found, 'f' - FEC Mismatch,
'P' - Protocol Error, 'X' - Unknown code,
'Z' - Reverse FEC Validation Failed
Type 'Ctrl+C' to abort

Success Rate is 100.00 percent (5/5)
round-trip min/avg/max = 1.37/1.67/1.98
