Hi,
I found the traditional BGP and MP-BGP are independent in bird, if use MP_REACH_NLRI, IPV4 NLRI are not used. Has any case that need to support traditional BGP and MP-BGP at the same time ? That mean have a configuration option that create UPDATE message with MP-BGP and traditional BGP, transmit IPV4 route and IPV6 route in one UPDATE message.
Hi Mixing traditional BGP and MP-BGP in one UPDATE is forbidden by RFC 7606, section 5.1. Of course, if you have BGP session with both IPv4 and IPv6, then both traditional BGP and MP-BGP can be used in one session, but not in one UPDATE. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
