VPLS fail -

[NOC_SouthTech_T]

In my log on switch x670-48x I have a lot of lines about this:

I don't know what is the problem. Ocurred after changes on MPLS Network.

I was performing some testing in an effort to replicate the same behavior but was unable to get the same log messages to generate. I was using 4 Summit X480 running EXOS 15.7.2.9.

After downing a link in the LSP of the L2VPN the path quickly converged with no notification of the PW losing signal. It may be best to have a case opened for further investigation.

Thank you so much

Follow bellow the topology. When occurs any change on LSP, the vpls turn down. After to find the new path is established again.

And the logs in both sides:

SouthTech,

Can you please provide more background on what changes were made. Are the VPNs down or traffic flowing through the VPNs affected? If so, it may be best to call in and have a case opened on this.
