Thanks for your replies.
This company will be a fairly large ASP.
The main thing I want is failover between the two routers. For outgoing
traffic you can setup HSRP, but for external customers accessing the company
I would have to setup BGP.
The actuall configuration is not my problem, it's the process of setting up
BGP with the ISP, that I don't know about.
Do you have to get your own AS number?
What is the usual cost of this procedure?
Thanks.
