MPLS IPV4/Pseudowire ping response

RouterOS Forwarding Protocols
1
  • Does RouterOS response appropriately to the ping mpls pseudowire or ping mpls ipv4 commands from a Cisco?

When testing this I get timeouts from the Cisco side even through the VC is up;

Mikrotik - Loopback Bridge - 10.0.2.14/32
Cisco - Loopback0 - 10.0.2.1/32
Link network - 10.0.2.32/30
Cisco side - 10.0.2.33
Mikrotik side - 10.0.2.34
OSPF is used between the two.

Mikrotik Side:

/interface vpls monitor 0
       remote-label: 26
        local-label: 45
      remote-status: 
          transport: 10.0.2.1/32
  transport-nexthop: 10.0.2.33
     imposed-labels: 26

Cisco Side:

show mpls l2transport vc 1307 det
Local interface: Vl1307 up, line protocol up, Eth VLAN 1307 up
  Interworking type is Ethernet
  Destination address: 10.0.2.34, VC ID: 1307, VC status: up

      Last remote LDP TLV    status rcvd: not sent
    MPLS VC labels: local 25, remote 45 
    Group ID: local 0, remote 0
    MTU: local 1998, remote 1998
    Remote interface description:

  VC statistics:

    packet drops:  receive 0, send 0

Everything looks good, and the Mikrotik is able to forward packets to the Cisco - I have yet to get the customer connected on the Cisco side but wanted to test return traffic and unfortunately I get timeouts on the ping mpls pseudowire command from the Cisco ( Other Cisco LDP/MPLS endpoints respond just fine from this box in the same MPLS cloud, so I know this Cisco box is fine ). Normal Ping works fine, pseudowire and mpls ipv4 do not… but the packets DO arrive at the mikrotik ( verified via traffic sniffer )

As far as I know it is a ping tool which requires specific support. We do not have such support implemented.

Roger that, we’ll attempt to pass traffic over it, if that works I’ll report back here advising that this is normal behavior in Cisco<->Mikrotik MPLS operation.

I can confirm that while these commands do not function from the Cisco side, the MPLS VC works just fine :slight_smile:
