OSPF Errors

[zimbawe998@mail.com]

Hi Guys,
We deliver 3 OPN box on a Layer 2 geographical MPLS.
Every time we restarted the frr daemon We receive this errors.
Jul 31 09:36:46   zebra[63820]: client 9 says hello and bids fair to announce only ospf routes vrf=0
Jul 31 09:36:44   zebra[62162]: Terminating on signal
Jul 31 09:36:44   zebra[62162]: client 9 disconnected. 0 ospf routes removed from the rib

Jul 30 16:53:43   zebra[95862]: Client 'rip' encountered an error and is shutting down.

If We do the same configuration with direct cable everithings working well.
Have you some suggestions for us to show the Layer 2 MPLS provider that he is doing some packet adjustments?

Our environment is based on OPN 19.7.1

Thanks

Does the provider support multicast over MPLS?

[zimbawe998@mail.com]

Technically speaking yes, because is a Layer 2 MPLS.
Is there some place to take logs os something else, packet capture laready shared, to show to provider to help to demostrate that is a Provider problems and not OPN?

Thanks

Best would be to put a switch between OPN and carrier equipment, then do a TAP and check if multicast are sent and received.

We discovered that it seems to be required to have the WAN interface on passive or active state, OSPF speaking.
Without this settings, no OSPF hello packets will go on the wire.....

[mimugmail]

You have to define the MPLS network so it starts sending hello's over it. Setting to passive doesn't make sense.

[zimbawe998@mail.com]

You are right.
But if we didn't set it passive, no hello packet go outside MPLS interfaces.
At the end We decide to switch back to static routing.
This behavior is not standard.
We tried with gateway failover.. it is working, not as expected but better than with frr routing.

Thanks to all
