Router Overview
The router is a multilayer Ethernet switching and aggregation platform. It is also a label edge router
(LER) that sits at the edge of a Multiprotocol Label Switching (MPLS) network. The router has links
that extend outside the MPLS network. It provides access and aggregation services for enterprise and
service providers.
Features and Capabilities
A scalable, carrier-class distributed forwarding router, the router is designed for the redundancy, high
security and availability, packaging, power and other requirements needed by service providers.
The router aggregates triple play and Ethernet service traffic from Gigabit Ethernet devices, aggregating
these services to 10 Gigabit Ethernet IP, MPLS edge, or core.
