How to Configuring Multiple Area OSPF

Complete first 4 lab when you find it you should configure OSPF OSPF a section a good foundation. Now it's time to build on this basis by learning how to configure OSPF to separate routing of network management and resource conservation benefits in many fields. Step back and look at it this way, the network uses multiple area is designed to provide easy access to network troubleshooting when things blow up. Facilities such as OSPF is one of zone 1, 2 are two OSPF areas of facilities, this allows you to isolate network issues to the level of a site/facilities.

Because in a certain region-specific router is configured only in the area of database, you can save the router resources. Area border routers maintain however these routers must be able to handle the whole OSPF topology such as catalyst 6,500 series routers, switches, 7,600 7,200 three thousand eight hundred-three thousand nine hundredths series integrated services router series routers, or even copies of performance requirements.

Show OSPF network contains an average of 50-75 area highly respectable Web site has done an online survey. Keep in mind that not every single building is its own OSPF area, general rule when designing an OSPF area is a single zone can contain up to 250 router and several hundreds of routes in the region.

Command to configure a new area is the same configuration as the backbone area 0 network statement following the specified range you specified a new area code. Remember region 0 is the backbone area and traversing a network from one region to another region that all communications must!!! Traversing the backbone area.

R2 ′ s in zone 3 point-to-point link between R2 and R3.
Each router its own OSPF area configuration Loopback0 interface, using a new OSPF area number of routers.
Configure point to point links between R4 and R5, and R4 and R5 ′ s physical LAN interface (FastEthernet0/0) in the OSPF area 45.
Verify that all new OSPF interarea routes in R1 ′ s routing table; these are called O*IA course.

Lab Instruction:

Step 1: Configure R2′s point-to-point link between R2 and R3 in Area 3.

Step 2: At each router its own OSPF area configuration Loopback0 interface, using a new OSPF area number of routers.

Step 4: Verify that all the new OSPF Inter-Area routes are in R1′s routing table; these are denoted as O*IA routes.
