Hi, Our routers speak OSPF and have a full mesh of BGP connections for our internal routes. This works quite well. One router sees the other through OSPF: 80.241.60.8/32 via 10.25.19.251 on bond0.19 [ospf1 2022-03-17] * I (150/2474) [80.241.60.8] Type: OSPF unicast univ OSPF.metric1: 2474 OSPF.metric2: 16777215 OSPF.tag: 0x00000000 OSPF.router_id: 80.241.60.8 The BGP session is established to 80.241.60.8 and e.g. this route is learned: 192.168.100.0/22 via 10.25.19.251 on bond0.19 [thor 2022-03-17 from 80.241.60.8] * (100/2474) [i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: BGP.next_hop: 80.241.60.8 BGP.local_pref: 100 In the first line the ospf_metric1 is shown: (100/2474) But when I try to filter on it (because I want to drop routes with a too high metric), the route attribute ospf_metric1 is "(void)". This seems to be because it's a BGP route and not an OSPF route. Is it somehow possible to achieve this? PS: This is with bird 1.6.8.
