Configure Routing Interfaces

The various router interfaces are the doors through which data travels on the network. Packets enter
through one interface, get processed and forwarded by the other router components, and exit through a
second interface. Packets can also be used or dropped by the router, and not forwarded through an
outgoing interface.
The following sections describe the physical components of the routing interface and the basic software
concepts and procedures used to configure interfaces:

Physical Components of Routing Interfaces

Two physical components that support routing interfaces are provided: the modular services cards
(MSCs) that provide the processing and forwarding capability, and the PLIMs that provide the physical
connections (ports) for the cables.
MSCs are also sometimes referred to as line cards.
Note
MSCs and PLIMs are installed as a matched set: PLIMs are installed on one side of the chassis, and the
MSCs are installed in a corresponding slot on the opposite side.
