This is my question

>>If yes how to set it?
The answer is "cannot have two default routers".
I "can" put 2 defaultrouter with
# route -a default xx.xx.xx.a 1
# route -a default xx.xx.xx.b 1
and if I do netstat -r I get message like
Destination Gateway Flags Refcnt Use Interface
localhost localhost UH 4 30364 lo0
default xx.xx.xx.a UG 4 0 le0
default xx.xx.xx.b UG 4 0 le0
but it use the first default entry for router and not automatically change
to second default entry when the first router down (I tried this).
I must delete the first default router manualy so it will use the second router.
I get some suggestion,
from Chip Christian:
To make automatically changing, do not use defaultrouter but use the
/usr/etc/routed, the daemon that manage/dynamically update the routing table
using RIP. This assuming the routers are broadcasiting RIP.
Just delete /etc/defaultrouter, /usr/etc/routed will run when the machine boot.
run a cron job every few minutes that pings the normal default router and if
it goes down, install a new default route.
