Currently we use a Cisco 2821 at the gateway for all the vlans and for the vlan routing. It also is our internet endpoint for vpn and tunnels. We are currently running a slew of dell 6200 series switches that we are replacing with cisco 2960's, and we also have 2 new 4900 series that are now going to handle all the vlans. My question is what do i need to do to the 2821 to clean up the things it don't need anymore. Do i need any new routes to point to vlans on the 4900?
attached are the configs.
