Cisco Express Forwarding --A Layer 3 switching technology. Cisco Express Forwarding can also refer to
central Cisco Express Forwarding mode, one of two modes of Cisco Express Forwarding operation. Cisco
Express Forwarding enables a Route Processor (RP) to perform express forwarding. Distributed Cisco Express
Forwarding is the other mode of Cisco Express Forwarding operation

line card --A general term for an interface processor that can be used in various Cisco products. For example,
a Versatile Interface Processor (VIP) is a line card for the Cisco 7500 series router.

MFIB --Multicast Forwarding Information Base. A protocol-independent multicast forwarding system that
contains unique multicast forwarding entries for each source or group pair known in a given network. There
is a separate MFIB for every logical network (VPN) in which the router is configured. Each MFIB entry
resolves a given source or group pair to an incoming interface (IIF) for reverse forwarding (RPF) checking
and an outgoing interface list (olist) for multicast forwarding.
