Using CLI to Execute a Ping with Explicit Outgoing Information

Use the ping sr-mpls fec fec-type igp isis CLI command to execute an IS-IS SR ping and the ping sr-mpls fec fec-type bgp CLI command to execute a BGP ping.

switch# ping sr-mpls 11.1.1.3/32 fec-type igp isis

Sending 5, 100-byte MPLS Echos to IGP Prefix SID(IS-IS) FEC 11.1.1.3/32,
     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 label entry,
  '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 Ctrl-C to abort.

Using CLI to Execute a Ping with Explicit Outgoing Information

Use the ping sr-mpls nil-fec labels comma-separated-labels [output {interface tx-interface} [nexthop nexthop-ip-addr]] CLI command to execute a ping.

For example, the following command sends an MPLS packet with the outermost two labels in the label stack being 2001 and 2000 out the interface Ethernet 1/1 with a nexthop IP address of 4.0.0.2:

switch# ping mpls nil-fec labels 2001,2000 output interface e1/1 nexthop 4.0.0.2 

It is mandatory that the nexthop is a connected nexthop; it is not recursively resolved.

The above CLI format is a simplified version. The [output {interface tx-interface} [nexthop nexthop-ip-addr]] is mandatory to be present in the VSH server. For example:

switch# ping mpls nil-fec labels 1,2 ?
output Output options
switch# ping mpls nil-fec labels1,2
^
% Invalid command at '^' marker.

Using CLI to Execute a Ping with Outgoing Information from an SRTE Policy

Use the following CLI command to execute a ping:

switch# ping mpls nil-fec policy name policy1
switch# ping mpls nil-fec policy endpoint 2.0.0.1 color 16 

Using CLI to Execute a Traceroute with Explicit Outgoing Information

Use the following CLI command to execute a traceroute:

switch# ping mpls nil-fec labels 2001,2000 output interface e1/1 nexthop 4.0.0.2

Using CLI to Execute a Traceroute with Outgoing Information from an SRTE Policy

Use the following CLI command to execute a traceroute:

switch# traceroute mpls nil-fec policy name policy1
switch# traceroute mpls nil-fec policy endpoint 2.0.0.1 color 16
