Hi all, I want to broadcast a last-resort old-school default route via RIPv1. The following config works: filter default_route { if net ~ [ 0.0.0.0/0 ] then { accept; } reject; } # ...snip... protocol rip { export filter default_route; interface "em0" { version 1; mode broadcast; update time 5; }; } ...but it only sends to the broadcast address of the main interface IP. How can I get it to send to the broadcast addresses of the aliases as well? These are the networks on the em0 adapter: x.x.x.192/28 (main) 192.168.x.0/24 (alias) 192.168.y.0/24 (alias) After consulting https://bird.network.cz/doc/bird-3.html#proto-iface , I tried the following to force additional/different addresses: interface x.x.x.193/28 { # actual interface IP/prefix interface x.x.x.192/28 { # network IP/prefix interface x.x.x.x { # interface IP only interface "em0" x.x.x.x { # interface name and IP interface "em0" x.x.x.x/28 { # interface name and IP/prefix All of these are rejected with the error "Interface name/mask expected, not IP prefix", regardless of whether I list the main interface IP, or main plus aliases (comma separated). Am I missing something simple in the syntax, or is the RIPv1 implementation not capable of doing this? Thanks in advance.
