We run a commercial ISP network that provides IP and other non-IP
services to our customers.
On top of that, our corporate/enterprise network is a customer.
Implementation is l3vpn with firewalls at each office sitting between
the l3vpn and public Internet. Enterprise and Internet traffic is routed
accordingly.
DCN network is a combination of l2vpn and l3vpn, depending on what part
of the network the DCN needs to touch.
