Hi, how do I propagate a default route into OSPF when a specific BGP session is up and not propagate it when it is down? Currently I have these config snippets: protocol static static_default { preference 10; route 0.0.0.0/0 unreachable; } function export_ospf() { if source = RTS_BGP then { return false; } if proto = "static_bgp" then { return false; } return true; } protocol ospf { rfc1583compat on; import all; export filter { if export_ospf() then accept; reject; }; area 0 { interface "ospf" { cost 10; hello 10; retransmit 5; dead 45; }; }; } protocol bgp ispa1 { description "ISP A1"; import all; export filter { if proto = "static_bgp" then accept; reject; }; local 1.2.3.6 as 1; neighbor 1.2.3.5 as 2; password "xyz"; } I can manually "birdc disable static_default" to not propagate the default route but how can this be automated when the BGP session to ispa1 is down?
