What would be the important requirements when choosing CISCO routers ?
I know that there are routers for small business / enterprise / data centers. But there are lots of models.
What are the factors that dictate the number of routers or models ?
Are there some on line sites that can filter the router models based on requirements ?
What I know is that there are different series depending on the usage.
For CORE routers there are the 7200, 7600, GSR-12000, CSR-1, CSR-3
For EDGE there are 2800/2900, 3800/3900
And for ACCESS 800/1800/1900
But I don't know what sets them apart, besides price that is.
