How do I configure BIRD to support multiple Linux kernel routing tables?









# cat /etc/bird.conf
protocol kernel main {
        learn;
        export all;
        import all;
        persist no;
}

protocol device {
}

protocol direct {
        interface "*";
}

protocol rip {
        export all;
        import all;
        interface "eth0", "eth1", "eth2", "eth3" {
                version 2;
        };
}





Thank you in advance.

I have found and tried a few different things on the web, but none seem to be doing what I want. I want to export routes from my "main" routing table (254) and an additional routing table "default" (253). Aside: I have multiple ip rules to cascade across multiple routing tables (local, main, reject, bogons, …, and finally default) looking for a match. I do this so that I can have Linux's routing stack handle various filtering for me. BIRD is successfully exporting routes from the main (254) routing table. I'd like to also export route(s) from the default (253) routing table. I have tried adding additional kernel protocols, including various incarnations of (kernel) table # entries and have had: syntax errors, references to required additional lines, and other unhappy things. So, will someone point me at a document that talks about how to work with multiple Linux routing tables?
