List of terms

3See local management interface (LMI) (page 75).

4See SNMP (page 123).

interior gateway protocol (IGP)

An Internet protocol used to exchange routing information with an

Autonomous System.

interim interswitch signaling protocol (IISP)

IISP provides interconnection between Nortel Multiservice Switch nodes as well as interconnection between Multiservice Switch and non-Multiservice Switch nodes (Nortel Networks-family nodes and devices from other vendors).

internal border gateway protocol (IBGP)

BGP configuration in which sessions are established between routers in the same autonomous systems (ASs). See also border gateway protocol (BGP) (page 20).

internal gateway

A DPN logical connection that runs over a Nortel Multiservice Switch trunk interconnecting two Multiservice Switch nodes in different RID subnets. A Multiservice Switch trunk supporting internal gateways continues to operate as a normal Multiservice Switch trunk in supporting non-DPN type of traffic.

internal reachable address

In PNNI networking, an address of a destination point that is directly attached to the logical node that advertises the address.

internal router

A router with all directly connected networks belonging to the same area. There can be internal routers in the backbone area if all of their interfaces are in the backbone.

International Telecommunication Union - Telecommunication Standardization Bureau (ITU-T)

A European standards body formerly called Comité Consultatif International Télégraphique et Téléphonique (CCITT).

Internet

A network of two or more networks. Usually these networks use different governing protocols or are administratively or physically separated.

Internet addressing

A system of addressing using a 32-bit address, usually divided into four octets.
