I have researched the hell out of Cisco's website and I'm still having trouble with making the right choice.
There will be 5Mbps links from the remote locations to the main location for a total of 20Mbps of WAN bandwidth being handled by the headend router. 2800 series routers at the remote sites and a 3825 as the headend would surely handle this (unless I'm mistaken).
But then I thought of scalability. There may actually be a need to increase the bandwidth up to 20Mbps per link in the future. I don't think the above choice of routers would handle this, but then I'm not experienced with WANs. So do I put a 3825 at each remote site and if so, what do I put at the main site?
Please please help or direct me to useful info. Thanks!
