Access Technologies
The Cisco 10000 series router supports routed bridge encapsulation (RBE) protocol. Point-to-point
protocol (PPP) access-based permanent virtual circuits (PVCs) is supported by using the following
PPP access encapsulation methods:
•
•
By using these PPP access technologies, the Cisco 10000 series router can terminate up to 32,000
sessions and support many features, including:
