Hello, This is probably fairly trivial but how can I tell bird (or Linux) that "connected routes" should have higher precedence than the routes from OSPF (even if they may be more specific)?
I have the following issue: I have a bunch of connected routers, connected via /31 links. There is also a loop. Now a Mikrotik OSPF node sends me a route (that it can reach) for a station that's actually directly connected. Unfortunately the system takes the OSPF route. But of course, the directly connected interface route should always be preferred. Example: # birdc show ospf neigh BIRD 1.6.8 ready. edge1: Router ID Pri State DTime Interface Router IP 203.0.113.193 1 Full/PtP 00:36 gre1 203.0.113.255 203.0.113.194 1 Full/PtP 00:37 wg1 203.0.113.225 # birdc show route | grep '203.0.113.22\(4\|5\)' 203.0.113.224/32 dev wg1 [edge1 2021-11-12] * I (150/0) [192.168.164.183] 203.0.113.225/32 via 203.0.113.255 on gre1 [edge1 06:18:20] * I (150/110) [203.0.113.194] # ip route list | grep '203.0.113.22\(4\|5\)' 203.0.113.224/31 dev wg1 proto kernel scope link src 203.0.113.224 203.0.113.225 via 203.0.113.255 dev gre1 proto bird Here we can see that to reach 203.0.113.225 (my desired endpoint), there are two routes: 203.0.113.224/31 which is the "connected route" set up automatically by Linux when I create the interface. And "203.0.113.225 via 203.0.113.255" which I receive via OSPF from a Mikrotik router which can also see this node. Even if the OSPF one is more specific, of course, I want the local connected route to have preference. Thanks!
