I am planning for an network upgrade.
Currently I have Cisco 2800 series router. I have BGP configured and also PfR configured. For BGP-PfR I have a cisco 2851 as Master controller and Cisco 2821 as border router.
I am planning to upgrade my existing routers with Cisco 3900 series. Now I would like to know around 10 imporrtant differences between Cisco 2900 series and Cisco 3900 series router.
It would be great if you could help me out with this.
