In CCNA programs, we often hear the phrase “OSPF routing intersection”. So what is the routing protocol and OSPF routing protocol configuration and how does it work? The following article will help you answer this question.
OSPF – Open Shortest Path First is a typical link-state routing protocol. This protocol is widely used in large enterprise networks. In this article, we will guide you through the basic OSPF routing protocol configuration. Follow the content below for more details.
Configure OSPF . routing protocol
Observing the diagram above you will notice the presence of 3 routers.
Router HN: interface serial0/3/0(s0/3/0) IP 192.168.1.1 connects to Router NA while interface f0/0 IP 172.16.1.1 connects to PC1
Router NA: interface serial0/3/0(s0/3/0) IP 192.168.1.2 connected to Router HN
Router HCM: interface serial0/3/1(s0/3/1) IP 192.168.2.1 connects to Router NA while interface f0/0 IP 10.1.1.1 connects to PC2
There are also 2 PCs present:
- PC1: IP 172.16.1.2, connected to interface f0/0 Router HN
- PC2: IP 10.1.1.2 connected to interface f0/0 Router HCM

For PCs:
- PC1: ip address 172.16.1.2, subnetmask: 255.255.255.0 gateway: 172.16.1.1
- PC2: ip address 10.1.1.2, subnet mask: 255.255.255.0 gateway: 10.1.1.1
Here, we have reviewed together basic operation of the OSPF . protocol in the CCNA program. This is a powerful, fast-converging protocol that can run on large-scale networks, and especially a standardized protocol that can be run on many product lines of many different manufacturers, so it is widely used in many industries. reality.
