I have an idea that you may want to test. How about disabling the ethernet
port from the switch? Try this and let me know if it works.

Subject: ISDN Backupinterface - Luxury problem...

Hi there!

I have a setup with the following...

R1---ETH---R2

using ISDN as backup link...

Only problem is that I can only get the ISDN backup to kick in if i
physically disconnect the ethernet cable connecting R1 and R2...

A "shut" command is not enough...

Since my lab is in a remote area it really annoys me to run to and
fromeverytime I wan't to test something...

Any good ideas on how to configure the ethernet interface so that the ISDN
will kick in when I do a shut in one end!

I have tried messing around with keepalives etc., but it does not seem to
have any effect...

Nic
