imagine. The fact that this sounds so troubling makes me think: Am I
doing something conceptually wrong?
How would one implement my scenario?

just export via a filter like this?
export filter {
if (net ~ [192.0.2.0/24{25,32}]) then {
accept;
}
reject;

Hello,
My BFD session between bird work fine but the ones but the ones to VyOS (which
uses FFR) just won't connect:
# birdc show bfd sess
BIRD 2.0.8 ready.

Hi,
I have two "border gateways" running bird; each establishes a BGP session to
the outside world. An internal router connects to each of the border gateways
and uses OSPF to exchange routes. (Note, other OSPF links may exist as well).
Both border gateways act as default gateways for the

Hi,
Is is somehow possible to export a larger prefix if one or more sub-prefixes
(subnets) are exported ... but also remove that prefix if no smaller subnet
exist any more?
Example: As soon as 192.0.2.44/32 or 192.0.2.208/28 (or any other prefix inside
192.0.2.0/24) is exported via eBGP, also
