About Topology

| Fig 2: OSPF Multiarea Lab Topology |
In the above diagram we have a lab in which there are multiples areas. Area 0 is the backbone area there are 4 others areas that are directly connected to the backbone area. All the routers of the other areas except area 0 have the loopbacks. Router 1 and 2 are the cores routers. Router 3,4,5 and 6 are the distribution layer routers and the others routers are the access layer routers. Loopbacks will be configured as the router ID. Following are the points of this lab that we have to cover:
- Multiarea OSPF Lab
- Loopback must be configured as router ID
- Perform Convergence
