Hi, I'me testing a network setup using multiple routing tables. I want to use this to setup different gateways. Some basic design is this: The system has two different uplinks (fast and slow for backup). And somewhere on the internet a colo with a full internet address range. I have setup the system with 2 giftunnels and use ospf over these for the internet range. This seems to be working. I want this to be configured with settings in rc.conf but failed to find the magic to do things like: setfib 0 ifconfig gif0 create 172.16.0.1 172.16.0.2 netmask 255.255.255.255 tunnel $extern_fast $colo I know setfib is not needed for the default routing table. setfib 1 ifconfig gif1 create 172.16.0.3 172.16.0.4 netmask 255.255.255.255 tunnel $extern_slow $colo and the routes: route add default $gateway_fast setfib 1 route add default $gateway_slow and use a third routing table for the ospf routing and pf to route traffic using the ospf announced routes. How would this be fitted in the rc.conf? for normal giftunnels i would use some thing like: gif_interfaces="gif0 gif1" gifconfig_gif0="$extern_fast $colo" ifconfig_gif0="inet 172.16.0.1 172.16.0.2 netmask 255.255.255.255" gifconfig_gif1="$extern_slow $colo" ifconfig_gif1="inet 172.16.0.3 172.16.0.4 netmask 255.255.255.255" But this won't include the setfib. For jails there is a setfib command using jail_<jname>_fib. I would like some thing like that also for routes, interfaces and deamons to start. I know i could set these things in a rc.local but would rather use rc.conf for configuration. Did any of you guys done something like this? Regards Robert
