MPLS OAM Support for BGP 3107
The MPLS OAM Support for BGP 3107 feature provides support for ping, traceroute and treetrace (traceroute
multipath) operations for LSPs signaled via BGP for the IPv4 unicast prefix FECs in the default VRF, according
to the RFC 3107 - Carrying Label Information in BGP-4. This feature adds support for MPLS OAM operations
in the seamless MPLS architecture deployments, i.e., combinations of BGP and LDP signaled LSPs.
Configure the Ping and Traceroute: Example
This section contains examples of the ping and traceroute commands, based on this topology.
This example shows multiple destinations set on the assigned LSP path.
RP/0/RP0/CPU0:router# show run int tunnel-mte 10
interface tunnel-mte10
ipv4 unnumbered Loopback0
destination 11.0.0.1
path-option 1 dynamic
!
destination 12.0.0.1
path-option 1 dynamic
!
destination 13.0.0.1
path-option 1 dynamic
!
!
This example shows an extract of the ping command.
# ping mpls traffic-eng tunnel-mte 10
Sending 1, 100-byte MPLS Echos to tunnel-mte10,
timeout is 2.2 seconds, send interval is 0 msec, jitter value is 200 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, 'd' - DDMAP
Type escape sequence to abort.
