The major purpose of our using Cisco Enterprise Routers is to terminate the 0.2 internet links because we don't use net features on the router. We prefer to configure NAS and other publishing through Cisco activities. We use the routers to create GRE channels with our different sites.
We use Cisco routers, firewalls, switches, and the Cisco Eyes and NAT solution in our environment. I have also done some R&D to implement mass cloud infrastructure for my client.
We're using the ISR series at the moment. The version is 4451 or 4431. These are public routers. We have permitted our major internet links on these routers.
This is an edge device for my organization. Normally, the enterprise company has one or two Cisco routers because they use it for internet termination and PLS termination.
I am using version 16.4 of the ISR router.
