Hi everyone,

I have a problem with my IPv6 peering sessions.
I use Quagga 0.99.20 on my router and one of my peers mailed me that the
session for IPv6 was suddenly down. And what I see is that both my
transit connections stay up just fine, but my 2 peerings sessions I have
are both down and it seems they both died at around the same time.

Total number of neighbors 5

Does anyone here have any idea what could be causing this?
Is their a known issue with IPv6 peering in Quagga 0.99.20?

When I restart the server, the sessions comes back up. Have not yet
tried restarting just BGPd because that would disrupt more then just
those 2 peering sessions.
