Armand,
Looks like the IGRP traffic is the interesting traffic from remote end.
As Brian wrote since there is no need for this traffic to dialin deny
this traffic at the remote end. Create a restrictive dialer list and deny
this traffic - may be dialer list 1 deny igrp any any or may be ip any
any ?
When u deny this traffic it wont dialin. There wont be a need as u are
using backup interface so when the local side (side where backup
interface cmd is placed) has physical interface in down state it will
dial out and establish connection.
Am i right ? this should work as u say snapshot routing is not
allowed.Which case study is this ?
Let us know.
Good Luck,[IMAGE]
Kasturi.
