Hi, I've run into a couple of gothas in the past week. This isn't so much a bug report, because everything is fine in -current. But I hope it might serve to save somebody some time if they stubble across it in the archives.
The first was experienced on a pair of 4.3 machines. Unlike any of our other transit feeds, we have one provider which appears to re-advertise our own prefixes back to our alternate routers. The routes are of course considered invalid because they are not loop free and it hasn't caused us problems previously. Except this week when applying an inbound filter with "softreconfig in yes" and "bgpctl reload". We observed all announcements matching these re-advertised prefixes to be withdrawn from all transit peers and not reannounced until the filter was removed. This behaviour was thankfully not replicated with 4.4 in the lab, so we'll be upgrading promptly. But we were having issues with our 4.4 peers keeping sessions open to each other. This was resolved with r1.13 of bgpd/timer.c. I'm curious though whether this will make it into the 4.4 errata as a reliability fix? Regards, Dan
