I have a question which I hope you can help with?
I have a Cisco 1841 acting as my core router(with HSRP to another 1841). Also attached to my lan(192.168.50.X/24) is a Zywall firewall (192.168.50.250). The firewall is my network D/G. What I want to do is use cisco's SLA monitor (to www.cisco.com) in order to tell my 1841 router if the main internet ADSL link is down. In the event of a failure, object tracking will then inject a new default route to pass traffic further down my network and out of another routers ADSL... I have an access list on the backup router stopping the main 1841 from accessing the web. So that the SLA monitor doesnt go live again ass soon as the backup route is in place.
Get the idea? :)
Everything works like clockwork... Apart from when the main adsl goes live again! because my D/G is now further down the network the 1841's SLA monitor never sees cisco.com as live, so never injects the original default route back into the network... Damn!
Basically, what I need to do is always send the SLA traffic to cisco.com out of fastethernet0/0.1 to my main firewall. I have thought about route-maps and as you can see from the example config I have tried applying a route map to the loopback0 interface and setting my SLA to coriginate from that interface. But it doesnt work... I dont see any interesting traffic when I do a sho route-map?
Any Ideas guys??? I have attached my config for your inormation. Thanks for any help :)
