===== 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
