Hello list,
I've run across an interesting issue which I think might be something I did
wrong but here goes. Below is my configuration file for bgpd.conf. I will
also give you the interface configurations for the two tunnels that I am
running. When I show the RIB using bgpctl show rib, I notice that the set
localpref parameter is not being applied properly to IPv6.

When I type bgpctl show rib, I see that the route selected for IPv6 traffic
is going through the neighbor fd40:cc1e:c0de::251 and not fe80::ade0.
Ideally, I'd rather have IPv6 go through the neighbor fe80::ade0 as that one
is on my continent. Below is an example from the show rib statement. I don't
even know why the fe80::ade0 address is not even showing up in the output.
*> V fd00:bb:5bf3::/48 fd40:cc1e:c0de::251 10 0 4242421955
4242423088 4242420549 i
V fd00:bb:5bf3::/48 :: 20 0 4242423914
4242420549 i
I have verified that the neighbor fe80::ade0 is actually getting a
connection and sending me route updates. Here is an example:
V fdff:feed:c0de::/48 :: 20 0 4242423914 4242420585
4242422980 210074 64719 65043 4242420138 i
Any ideas?
Thanks,
Matt
