Synopsis: <BGPD route decision problem when multiply paths available> Category: <user i386 system> Environment: System : OpenBSD 5.4 Details : OpenBSD 5.4 (XXX) #7: Thu Mar 13 10:08:46 MSK 2014 [email protected]:/usr/src/sys/arch/i386/compile/XXX
Architecture: OpenBSD.i386 Machine : i386 Description: I have noticed that bgpd does not setup the backup route when primary one withdrawn if both VPNv4 prefixes has different RD. (waited about 30 minutes, must be instantly) How-To-Repeat: peer1 ---> bgpd <--- peer2 Peer1 advertised prefix which becomes best on bgpd for some reasons, peer2 advertises the same prefix as backup. Both prefixes has different RD but has equal route-targets. When primary route goes away rdomain catch it and delete the route from FIB, but does not install backup route. The peer2 continues to announce that to bgpd, but route will be installed only if i trigger that prefix refresh on peer2 Fix: Didnt find any workarounds.
