Hi all, I apologize if this topic has already been discussed on the mailing list, but I couldn't find a message archive to check it out. And, I apoligize for my poor English. My problem is that the BIRD RIPv2 daemon doesn't accept a worse metric coming from the router which is the nexthop for that entry. I'll paste some sniffed packet to give the whole idea. This network is very simple - 2 routers (200.0.0.1 and 200.0.0.2) with 4 interfaces each: Frame 1 (106 bytes on wire, 106 bytes captured) Internet Protocol, Src Addr: 200.0.0.1 Dst Addr: 224.0.0.9 Routing Information Protocol IP Address: 200.0.6.0, Metric: 2 IP Address: 200.0.5.0, Metric: 2 IP Address: 200.0.4.0, Metric: 2 /* The metric is 2. */ Frame 3 (106 bytes on wire, 106 bytes captured) Arrival Time: Jun 16, 2004 18:19:14.496397000 Internet Protocol, Src Addr: 200.0.0.1 Dst Addr: 224.0.0.9 Routing Information Protocol IP Address: 200.0.6.0, Metric: 5 IP Address: 200.0.5.0, Metric: 5 IP Address: 200.0.4.0, Metric: 5 /* Here I changed the default metric to 5. And now 200.0.0.1 begins announcing its directly connected networks with a metric of 5; anyway, 200.0.0.2 (whose hostname is r1) doesn't change the metric in its route table as you can see below: r1:~# birdc BIRD 1.0.6 ready. bird> show route 127.0.0.0/8 dev lo [direct1 18:12] (240) 200.0.0.0/24 dev eth0 [direct1 18:12] (240) 200.0.1.0/24 dev eth1 [direct1 18:12] (240) 200.0.2.0/24 dev eth2 [direct1 18:12] (240) 200.0.3.0/24 dev eth3 [direct1 18:12] (240) 200.0.4.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- 200.0.5.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- 200.0.6.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- I left the arrival time information in the second packet to let you compare it with the time displayed in the show route output.
