I have a router running BIRD. It is connected to network A using eBGP and B using OSPF. I want to let network B have routes to network A as another area (i.e. this is an area border router). How to achieve this?
Already tried adding the following to OSPF network B block:
area 1.2.3.4 {
default cost 100;
external {
<Network A prefix>
};
};
};
but seems to be no use.
