Hi I need to alter the next_hop for IPv6 prefixes advertised over IPv6 eBGP. I'm using a filter that says "bgp_next_hop = x:x:0:1c::1 ;". And it is seen in the birdc6 with: show route all <filtername> as BGP.next_hop: x:x:0:1c::1 but on the line I see: Next hop: x:x:0:1c::2 (16) #The GUA of the router Next hop: fe80::230:48ff:feba:6b17 (16) #The LL of the router which also is what I see on the receiving cisco. Has this behavior changed? i believe I had this working in bird-1.2.5 I'm now running bird-1.3.5 on Debian Lenny. What I'm really looking for is a way to only send a manually set globally unique address and no link-local. When I read the bird docs, it seems odd that this is referred to as a "improper bgp update". My interpretation of rfc2545 section 3 is that link-local is optional. It's not at all clear on how a receiver should treat an update with both LL and GUA NHs. My general feeling is that what was simple in IPv4, is not thought through in IPv6. /Tias
