[ris-int] not saving keepalives in quagga dumps?

Hi all, recently we had a session that went down without our quagga noticing it. The remote peer told us the session was down (while our quagga said it was up). We had to clear the session to restore it. It seems that this was caused by our hold time of 0. If the peer just suddenly drops, quagga has ofcourse no way of knowing this and will see the session as up. As it's already up, it will refuse connection attempts from the remote peer. I don't know how often this happens. I think quite some of our peers do not closely monitor peering sessions and therefore similar events will probably go unnoticed. I think it would be best to set the normal hold time for all peerings to prevent this from occuring. I heard from Arife that we don't do that now, to prevent polluting our dump files with loads of keepalives. As far as I can see, there is no option to skip keepalives in the dumps, but I was thinking we should be able to write a patch to do so, or ask quagga-users whether someone did something like it already. So my idea is: - get quagga to stop dumping the keepalives - set all peerings to a hold time of 180 Any comments? cheers, -- Erik Romijn RIPE NCC software engineer erik at ripe.net http://www.ripe.net/ -------------- next part -------------- A non-text attachment was scrubbed...
