MX80 issues with OSPF

[ Edited ]

I have OSPF configured between a M10i and an MX80, it has been working without issues for more than a month but since a couple of hours back i have issues where the OSPF is timed out. The following message appears in the logs on both routers:

 

May 12 11:39:40  sto1-b15-ro01 rpd[1213]: RPD_OSPF_NBRDOWN: OSPF neighbor 11.11.11.11 (realm ospf-v2 ge-1/0/0.52 area 0.0.0.0) state changed from Full to Init due to 1WayRcvd (event reason: neighbor is in one-way mode)
May 12 11:39:41  sto1-b15-ro01 rpd[1213]: RPD_OSPF_NBRUP: OSPF neighbor 11.11.11.11 (realm ospf-v2 ge-1/0/0.52 area 0.0.0.0) state changed from Init to ExStart due to 2WayRcvd (event reason: neighbor detected this router)
May 12 11:39:41  sto1-b15-ro01 rpd[1213]: RPD_OSPF_NBRUP: OSPF neighbor 11.11.11.11 (realm ospf-v2 ge-1/0/0.52 area 0.0.0.0) state changed from Loading to Full due to LoadDone (event reason: OSPF loading completed)

I have verified that the link is up at all times, i have a ping running from both ends to the opposite physical interface (addresses 11.11.11.11 and .12) and i see no issues there. When i ping lo0.0, it intemittently goes down and takes the BGP with it since it's configured between the lo0 interfaces.

 

The MX80 is running junos 10.4R3.4 and the M10i is running 10.3R1.9

Are the routers connected together with a patch lead, or a carrier service?

 

lo0.0 and your BGP session will be going down every time OSPF does, because the route is no longer visible.

 

Do a "show interfaces ge-1/0/0 extensive" and check for interface errors.

Thanks for your reply, the routers are connected via carrier service and I was just informed by the carrier that they are having issues in the transmission path (I opened a ticket with them when this issue appeared). Due to some issue with failover in the redundant ring between the nodes, packets are intermittently lost.

I have encountered a very similar issue with MX80 running 10.4R3 as well.

Once in a while it shows the same logs with several neighboring routers on a shared VLAN, but in our case it happens for OSPFv3.

 

Also in my setup they are connected through a switch.

 

I have opened a TAC case about it and waiting for them to finish analyzing all the logs and data.

Did you get any reply from JTAC on you case? We been seeing the same issue onour routers too.

This turned out to be a issue with our wan carrier; their ethernet wan equipment (extreme switches directly on dwdm) ran into an issue which impacted ospf multicast traffic. Not sure if it was all multicast traffic or only ospf multicast -related traffic. Once they resolved the issue (reboot affected equipment and then later on patched the switch software) the problems went away again, without any changes on our side.
