Basic load balancing and fault tolerance on Cisco Router
What we have,
Two T-1's to the Internet,
Cisco 3620 w/two WIC's, T-1 CSU/DSU
IOS Version 12.0(7)T
I want to set up basic load balancing and fault tolerance for these two connections. Can I round-robin my outgoing connections and also configure the router to redirect all traffic should one T-1 go down? We do no hosting here, so we are only concerned with internal user connectivity to the Internet.
