I'm running OpenBSD 4.2 on SPARC64. I have managed to get a simple BGP setup
working on IPv4, however the IPv6 version of the same setup fails. A BGP
session is established in both cases and peer B claims to be announcing what it
should be announcing, yet in the IPv6 version peer A does not add it to its RIB.
Host A:
