Hello bird community, I have a little problem with some configuration files in Bird 2.0 The protocol I use is BGP I have a star network with 5 nodes, one in the center with the 4 edges. It's something like this (I'm not sure you will see it correctly): H1 | H2--H0--H3 | H4 Now H1,H2,H3, and H4 will share a network, a basic /24 network, and H0 should share them with these rules: If the network comes from H2 I share it with H1 and the opposite If the network comes from H3 I share it with H4 and the opposite For this reason, I created this configuration for the H1-H0 link: protocol bgp h_0_h_1 { local 10.0.0.1 as 1; neighbor 10.0.0.2 as 2; ipv4{ import filter bgp_in; export where proto = "h_0_h_2"; }; direct; } Obviously, the protocol "h_0_h_2" is the protocol between H0 and H2 that is the same with little differences in addresses and in the export, where proto = "h_0_h_1". I don't think this is the correct way to handle this situation, could you please suggest any other configurations? Thanks a lot for the help, Mattia -- Mattia Milani
