MPLS Overview for ACX Series Universal Access Routers
Multiprotocol Label Switching (MPLS) provides a mechanism for engineering network
traffic patterns that is independent of routing tables by assigning short labels to network
packets, which describe how to forward them through the network. MPLS is independent
of any routing protocol and can be used for unicast packets. On the ACX Series routers,
the following MPLS features are supported:
•
The configuration of a label-switching router (LSR) for processing of label-switched
packets and forwarding of packets based on their labels.
•
The configuration of an ingress label edge router (LER) where IP packets are
encapsulated within MPLS packets and forwarded to the MPLS domain, and as an
