We have two routers. The ethernet interfaces are combined for LAN and WAN.
both sides are connected via a wireless link.
for back-up of the Wireless link, the isdn is used.
The isdn link comes up if the route to 172.16.0.0 or 172.17.0.0 goes down, this is tested and worked well.
seeing the bill of the telco the last two months the isdn link was gone up and down many times, while the wireless link was okay.
can someone help me and see of the configuration is okay?
Could it be a RIP problem?
Please help me further?
thanks,
Michiel IJff
