[quagga-users 12574] Re: IPv6 Peering sessions down

Hi,

I did some more troubleshooting.

I tried to reset the session using clear, but this didn't help anything.
I threw the neighbour config away and recreated it, this didn't fix the
problem.
I restarted the BGPd process. This didn't fix the problem.

What I see all the time is that the other side send packets to open the
session and then my router doesn't respond to those messages.

Anyone here seen something like this before?
