I've a branch office wan connected to the main site using only static routing.
In the same router, Cisco 1760-V, I've an Adsl Internet connection with a VPN configured to the main site.
We'd like to use this link only when the primary wan connection is out of order.
Into main site my customer want to change static routing manually but he'd like to do it automatically into branch.
Is it possible?
May I use rtr or tracking to monitor a reachability of an host into main site and change routing ?
I've seen OER but it seams a quite complicated for this !

Hi,
There is an easy way to do it.
rtr (or ip sla in latest versions) and track is the best way to do it.
If you search on the cco you will find many topics descriping how you can achived it.
Check the following as a sample config :
ip sla monitor 1000
type echo protocol ipIcmpEcho 1.1.1.1 (remote loopback) source-ipaddr 2.2.2.1 (loopback interface)
timeout 1000
owner DAFNI
tag DAFNI-CENTRAL
frequency 15
hours-of-statistics-kept 12
distributions-of-statistics-kept 10
buckets-of-history-kept 5
ip sla monitor schedule 1000 life forever start-time now
track 10 rtr 1000
ip route 1.1.1.1 255.255.255.255 dialer 10 (dsl int)
ip route 192.168.1.0 255.255.255.0 dialer 10 track 10 (if track is ok all traffic to 192.168.1.0 will go from the vpn)
ip route 192.168.1.0 255.255.255.0 dialer 20 200 (ISDN backup int )
hope this helps

Why don't you use dynamic routing such as EIGRP?
THis can solve the problem by having the primary interface with higher bandwidth and the DSL interface with lower bandwidth. Therefore, you will be using the first link as primary and the other secondary.
