How can you configure Multiarea OSPFv2 in a routed network?

How can you configure Multiarea OSPFv2 in a routed network?

Part 1: Configure OSPFv2

1. Step 1: Configure OSPFv2 on R1. Configure OSPFv2 on R1 with a process ID of 1 and a router ID of 1.1.
2. Step 2: Advertise each directly connected network in OSPFv2 on R1. Configure each network in OSPFv2 assigning areas according to the Addressing Table.
3. Step 3: Configure OSPFv2 on R2 and R3.

Why would multi-area OSPFv3 be used?

Using multi-area OSPFv3 in large IPv6 network deployments can reduce router processing cycles by creating smaller routing tables and requiring less memory overhead. In multi-area OSPFv3, all areas are connected to the backbone area (area 0) through area border routers (ABRs).

What are the features of multi-area OSPF?

The Features of Multi-area OSPF

• Router Types.
• Link-State Advertisements.
• Different Types of Areas.
• ABR LSA Propagation.
• OSPF Path Selection Between Areas.
• Calculating the Cost of a Path to Another Area.
• Capacity Planning in OSPF.
• Number of Neighbors per Router.

Why do OSPF serial interfaces usually require manual bandwidth configuration?

Why do OSPF serial interfaces usually require manual bandwidth configuration? * OSPF uses the bandwidth value to compute routes for its routing table. * It improves the routing efficiency by reducing the routing table and link-state update overhead.

What is the main disadvantage of multi area OSPF?

Assuming proper OSPF design and configuration, using multiple area concept brings vanish these disadvantages: In multiple area concept updates are kept within an area. They are not extend to other areas. Therefore routers affected by change are only within an area.

Which characteristic describes both ABRs and ASBRs that are implemented in a Multiarea OSPF network?

Which characteristic describes both ABRs and ASBRs that are implemented in a multiarea OSPF network? They are required to perform any summarization or redistribution tasks. What type of OSPF LSA is originated by ASBR routers to advertise external routes?

Which area is referred to as the backbone area?

The backbone area (also known as area 0 or area 0.0. The backbone area is the logical and physical structure for the OSPF domain and is attached to all non-zero areas in the OSPF domain. The backbone area is responsible for distributing routing information between non-backbone areas.

What is Asbrs?

An Autonomous System Boundary Router (ASBR) is a router that is running multiple protocols and serves as a gateway to routers outside the OSPF domain and those operating with different protocols. The ASBR is able to import and translate different protocol routes into OSPF through a process known as redistribution.

How do I know if my router has Abr?

Area Border Router ( ABR ) : A Router is said to be area border router if it’s minimum one interface is in OSPF AREA 0 and other interfaces can be in any area ( Area 1 – Area 2^32-1 ).
