Hi
As said, I'm new to BIRD and struggling a bit with the config syntax.
I'll try to explain what I want to do.
I have a few prefixes, lets say 10.1.1.0/24, 10.2.2.0/24, 10.3.3.0/24.
I want to announce these (and only these) in a BGP session, but with a
modified next hop.
How would I do this?
Add this export filter to you BGP session:

export filter {
	if net ~ [10.1.1.0/24, 10.2.2.0/24, 10.3.3.0/24] then {
		bgp_next_hop = X.X.X.X;
		accept;
	}
	else reject;
};

(I did not check syntax, maybe some ';' is missing.

Any help is much appreciated.
