VPLS Interface flapping

Hi,

i have a problem with a VPLS Tunnels which goes occasionally down and after about 5 seconds up again.

The two tunnel endpoints can ping each other even during the issue. We have two wireless bridges between the tunnel and it only happens at the second one. OSPF/MPLS is setup as in some other sites where we have no problem at all.

What would you check to solve this issue? Poor wireless link, mtu, ospf? I need some hints which logs etc. to look for…

Thanks

Andy

Poor wireless link would be the first thing I would check, look for OSPF flapping.

Which equipment is used on the PTP? are there switches between the two routers running the VPLS tunnel??
