Hi,
I'm confused with what is going on with this.
Here are the config snippets for what I am doing:
this sets up the bgp peer that I am monitoring:
template bgp tocore {
description "bgp to data center as";
local as 65304;
direct;
export filter inside_export;
import filter inside_import;
next hop self;
bfd on;
}
protocol bgp inside_netA from tocore {
neighbor 10.12.0.3 as 65304;
source address 10.12.0.11;
}
this is the bfd config:
protocol bfd {
interface "edge*" {
interval 300 ms;
multiplier 3;
};
interface "net*" {
interval 300 ms;
multiplier 3;
};
}
Other than not defining any neighbors directly, it looks just like the
docs as far as I can tell.
BGP is working, the peering is established and the routes are passing
correctly.
here is the show protocols all from birdc:
bfd1 BFD master up 13:16:07
Preference: 0
Input filter: ACCEPT
Output filter: REJECT
Routes: 0 imported, 0 exported, 0 preferred
Route change stats: received rejected filtered ignored

This machine is .11 and the juniper is .3 on the 10.12.0 net. Here is
the tcpdump output:

and so on
So clearly from tcpdump bird is always saying down and so nothing is
setting up. What do I need to do. This is running 1.6.0 right now.
