[cisco-bba] VPDN session stuck in wiccn state ?

[Andy Saykao]

Hi Tony,

Thank you for your reply.

> One thing I can see from your output is that all of the sessions with
this state are on the same tunnel (TunID: 21116). Do you have any other
sessions that are working on this same tunnel ?

Yes there are valid sessions on the tunnel.

> Is it happening across all of your LNS, or just one ? When you
upgraded did you change IOS ? What IOS version are you running ? Have
you tried a different IOS ? Does a reboot fix the problem ?

It's happening across all of our LNS's. We've been working extensively
with Cisco to get these LNS's up and running and using a special
engineering release from the 12.2(33) train. No, we have not tried a
different IOS given that we've been working with Cisco on getting this
far already. 

A reboot fixes the problem temporarily but when we arrive the next day,
there's a whole bunch of sessions waiting for us stuck in this "wiccn"
state.

We terminate a few tunnels from a variety of Service Providers on these
LNS's and are currently only having issues with one provider where we
encounter this problem.

Cheers.
