[j-nsp] VPLS NSR in 9.1

[Marlon Duksa]

Does anyone have experience with Non Stop Routing in 9.1 for VPLS? Release
Notes says that VPLS NSR is supported but in our case we clearly see packet
drops, as a matter of fact traffic does not even recover after a failure.

We have LDP signaled and BGP signaled VPLS (single VPLS instance) and after
we reset the active RE, the MX960 sends LDP Withdrawal message to the LDP
peer and BGP Update msg to the BGP peer. Aren't the states supposed to be
synchronized between two REs in NSR case? Peers should have no knowledge of
the RE failure.

In the same setup we run (IPv4) BGP and ISIS and those two protocols are
just fine with NSR.


Thanks,
Marlon
