===== Policy based routing in FreeBSD ===== **Status:** not testet, maybe not complete ==== Problem ==== If you have multiple interfaces on a based router, with multiple default routes (in this case two), dynamic routing with BGP or OSPF, have multiple routing tables and want traffic from a specific subnet to use a specific default route, with Linux you will do something like this: * setup default route for the router into the default routing table * setup dynamic routing protocols with bird * export routes into a second routing table * export second default route received via a dynamic routing protocol, into a third routing table * setup policy routing with ip rule * redirect all traffic to the second routing table (the one without a default route) * if no route matches: redirect traffic from specific subnet to third routing table * last rule: redirect traffic to default routing table ==== Solution ==== maybe with ipfw setfib * ==== Usefull links ==== * Unordered List Item ==== Todo ==== graphic for illustration
