Routing between two or more logical areas. Contrast
with: intra-area routing. See also: area.
Any of several processor modules used with Cisco 7000
series routers. See also: AIP, CIP, EIP, FEIP, HIP, MIP, and TRIP.
Interior Gateway Routing Protocol (IGRP)
Cisco proprietary distance-
internal route processors
Route Switch Modules (RSM) and Route
Switch Feature Cards (RSFC) are called internal route processors because the
processing of Layer 3 packets is internal to a switch.
The global "network of networks," whose popularity has
exploded in the last few years. Originally a tool for collaborative academic
research, it has become a medium for exchanging and distributing informa-
tion of all kinds. The Internet's need to link disparate computer platforms
and technologies has led to the development of uniform protocols and stan-
dards that have also found widespread use within corporate LANs. See also:
TCP/IP and MBONE.
Before the rise in the use of the Internet, this lowercase form was
shorthand for "internetwork" in the generic sense. Now rarely used. See
Any protocol belonging to the TCP/IP protocol stack.
See also: TCP/IP.
Any group of private networks interconnected by routers
and other mechanisms, typically operating as a single entity.
Broadly, anything associated with the general task of
linking networks to each other. The term encompasses technologies, proce-
dures, and products. When you connect networks to a router, you are cre-
ating an internetwork.
Cisco has created the proprietary protocol Inter-
Switch Link (ISL) to allow routing between VLANs with only one Ethernet
interface. To run ISL, you need to have two VLAN-capable Fast Ethernet or
Gigabit Ethernet devices like a Cisco 5000 switch and a 7000 series router.
