Packet loss inside VPLS, but not out?

Sun Mar 14, 2010 2:59 am

We have configured MPLS as per example on Wiki. We have many VPLS setup. They work good, but on occasion (random times) we will see about 5 seconds of completely 100% packet loss inside the VPLS tunnel. Outside the tunnel there is not a single packet dropped. Sometimes the entire VPLS interface will go down and come back up. disable-running-check=yes does make the interface not go down, but we still see the packet loss.
Because it's almost exactly 5 seconds, it seems like maybe it's something timing out, not getting a hello, or...? Any ideas? It's causing us much frustration.

Hi spectrasurf, did you ever find a resolution for this? We are seeing a very similar problem with BGP based VPLS circuits and also routed MPLS. This is resulting in between 0.5 and 1% packet loss on the circuit yet outside between loopbacks there is no packet loss. Any assistance appreciated.
