inter-area routing
Routing between two or more logical areas. Contrast
with: intra-area routing. See also: area.
interface processor
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-
vector protocol.
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:
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
also: internetwork.
Internet Protocol
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.
inter-VLAN routing
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.
