Hi
I have a scenario for testing on JunOS and IOS XE. based on this scenario, The routing domain is divided on JMX and MPLS is running all over the routers. (The following diagram shows the scenario. The configuration and outputs were attached.)
Now the point is everything works fine but something bothers me here.
On JMX the interfaces inside of Instance are not shown as MPLS-enabled but MPLS traffic is passed over them without any issue.
jcluser@vMX1> show mpls interface
Interface State Administrative groups (x: extended)
gr-0/0/10.10 Up <none>
ge-0/0/0.23 Up <none>
ge-0/0/0.32 Dn <none>
jcluser@vMX1> show mpls interface instance OSPF2
MPLS instance is not running
This output shows interface
ge-0/0/0.34 and
ge-0/0/0.35 in
Instance no-forward OSPF2 are not MPLS enabled. Also, MPLS ping from R05 to JMX returns F code:
Core_CSR#ping mpls ipv4 10.234.247.3/32 source 10.234.247.5Sending 5, 72-byte MPLS Echos to 10.234.247.3/32, 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,'l' - Label switched with FEC change, 'd' - see DDMAP for return code,'X' - unknown return code, 'x' - return code 0Type escape sequence to abort.FFFFFSuccess rate is 0 percent (0/5)Total Time Elapsed 24 msI must note again:
1- everything works fine and the L2VPN sessions between have no issue from every router to every router.
2- MPLS LDP ping from the routers inside of Instance OSPF2 to JMX fails.
3- MPLS LDP ping from the router inside Instance master to JMX works fine.
4- Another way around always works fine and JMX can do MPLS LDP ping all routers without issue.
5- This behavior can be seen in the attached text files.
Would you please help me out?
Thank you
