Subject: [c-nsp] route availability

Hello,

I currently have a four default routes on a 2621 router that is doing
load balancing to four adsl modems/routers (which are doing NAT).

ip cef

ip route 0.0.0.0 0.0.0.0 192.168.11.251
ip route 0.0.0.0 0.0.0.0 192.168.11.252
ip route 0.0.0.0 0.0.0.0 192.168.11.253
ip route 0.0.0.0 0.0.0.0 192.168.11.254

This is working for load balancing, but when one of the modems stops
working I basically loose all connection to the internet.  What would be
the best way to verify the availability of the next hop?

Thanks,
Dan.
