Consequently, what is an area in OSPF?
An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification. A router within an area must maintain a topological database for the area to which it belongs.
Also, why is multi area OSPF used? Multiarea OSPF is useful in larger network deployments to reduce processing and memory overhead. Multiarea OSPF requires a hierarchical network design. The main area is called the backbone area (area 0) and all other areas must connect to the backbone area.
Additionally, how do I set a single area OSPF on my router?
Configuring OSPF in a Single Area
- Use the command router ospf process ID to start OSPF.
- Use the network command to enable the interfaces.
- Identify area assignments.
- (Optional) Assign the router ID. Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0. The network command network 0.0.
What is OSPF protocol and how it works?
Routers connect networks using the Internet Protocol (IP), and OSPF (Open Shortest Path First) is a router protocol used to find the best path for packets as they pass through a set of connected networks. The OSPF routing protocol has largely replaced the older Routing Information Protocol (RIP) in corporate networks.
