MPLS neighbourg disconnects

Tue Jul 27, 2010 10:37 am

I got a strange problem in my MPLS cloud

one of my core routers is a 750g with a bulletM5 on port 4

Remote side is 433AH with R52 radio

Signal is -70, CCQ is 80% +

OSPF on network, there is about 800 routes in the routing tables, but all is stable

I have about 50 MPLS layer 3 clients in the mpls network, all is stable but this link

Every random time i notice my mpls ldp neighbour disconnects and reconnect, takes about 5-10 sec, could this be load related?, there is no change in ospf states or routing table

i've even added routes on both routers with a static route to each lobridge IP address to ensure its stays up, but still not

Could the problem be Mikrotik station - > ubnt(accesspoint-wds) problem?

i've tried combination , using vlan's etc, but still the same, problem is somehere else

My MT versions is 4.10

ANy advice would be appreciated

Thanks

/mpls ldp neighbor

By "managed to get it more stable" do you mean that neighbor is not "flapping" any more? This seems to be issue somehow related to OSPF. It would be very handy if you sent a few supout files to support, made with some time interval, e.g. 5min (so that some number of flaps would have happened). Refer to this topic as well, please.
