My Cisco 3825, (ISR?) is running fine now, thanks to a lot of help. We've now gotten another WAN link from a different ISP for redundancy.
What I need is to know how to configure the router to be able to Fail Over if the main link has an issue. I don't want to load balance.
- Is this possible?
- If so, how, e.g. commands/code to implement this
I've seen something called HSRP, but the article seemed to only reference Catalyst devices, so I'm not sure if it's a thing on my router, and also, it seems to deal more with multiple routers, not a single one with two WAN links.
I will also need to purchase another card to add a port for this new connection, could someone tell me exactly what I'd need?
