We've two full bgp tables in our border routers (275K+ prefixes per table). The quagga version we use get's real busy if one of our BGP peers disappears suddenly. It starts recalculating the routing table and neglects the BGP sessions. Sometimes the other BGP sessions time-out, then we lose every route. The OpenBGPD BGP daemon is split in three threads and doesn't have this problem. Regards, -- Peter Spekreijse E: peter@spekreijse.net T: +31-742672764 M: +31-641922460
