What does Inter area mean?

interarea (not comparable) Between areas.

What is Asbr in networking?

Autonomous system border router (ASBR) A router that is connected to one or more logical entities (AS), usually through an exterior routing protocol such as BGP.

What are inter-area routes?

Solved: OSPF Difference inter-area and intra-area routes – Cisco Community.

What is the different between inter and intra?

Although they look similar, the prefix intra- means “within” (as in happening within a single thing), while the prefix inter- means “between” (as in happening between two things).

What is Asbr and ABR?

ABR is a router used to establish a connection between backbone area and other OSPF areas. ASBR is a router that is connected to other OSPF areas, as well as other routing protocols such as IGRP, EIGRP, IS-IS, RIP, BGP, Static.

What is OSPF area?

By definition an OSPF area is a collection of networks, not a collection of routers. A backbone network segment is an IP subnet that belongs to the area identified by 0.0. 0.0. Areas that are not physically connected to the backbone are logically connected by a backbone ABR using an OSPF virtual link.

Why do we need AREA 0 in OSPF?

Albeit OSPF is a link state protocol, the way OSPF handles inter-area traffic leaves it prone to routing loops. This is why OSPF must connect back to area 0 – to avoid routing loops.

What is NSSA area in OSPF?

The OSPFv2 not-so-stubby area (NSSA) enables you to configure OSPFv2 areas that provide the benefits of stub areas, but that also are capable of importing external route information.

What is the difference between Inter-area and intra area?

Note: Intra-area routes refer to updates that are passed within the area. Inter-area routes refer to updates that are passed between areas. In order to reach the outside networks, the routers in the stub area use a default route which is injected into the area by the Area Border Router (ABR).

What is an example of inter?

Inter- is a common prefix that means between or among groups. For example, the interstate highway is a road system that goes between states, connecting them together. Similarly, the word international means between or among nations.
