You will certainly have to do this on different IP's.
And actually I only do it with different IP's in different netmasks.
I think this config is exactly what's requested.
It was written for use on FreeBSD (using multifib).
At one point I got collisons, and I did all my best to prevent that (with
success).
So probaly you can make it more simple.
The compact version of bird.conf would be:
table as1;
table as2;
listen bgp address 10.0.1.102 port 179;
listen bgp address 10.0.2.102 port 179;
protocol static stat_net1 {
table as1;
route 192.168.3.0/24 via "em0";
}
protocol static stat_net2 {
table as2;
route 192.168.188.0/24 via "em0";
}
protocol bgp COMPANY1 {
table as1;
router id 10.0.1.102;
local 10.0.1.102 as 1;
neighbor 10.0.1.101 as 69;
direct;
export where proto = "stat_net1";
}
protocol bgp COMPANY2 {
table as2;
router id 10.0.2.102;
local 10.0.2.102 as 2;
neighbor 10.0.2.101 as 69;
direct;
export where proto = "stat_net2";
}
I'm very curious to hear any comments, or see different approaches.
Leo.
