(The Construction of OSPF Dynamic Routing Network
1. Network description
OSPF routing protocol is the most commonly used dynamic routing protocol in enterprise-level networks. Now, we will introduce the configuration and status of Huawei routers running OSPF with the following simulation networking. They are respectively connected to the lower three routers.
2. Network diagram
The core router 2631A is connected to the 2631B through the serial port in the PPP mode, with the 2631C in the HDLC mode, and with the 2631D in the X.25 mode. Each serial port of the router and the Ethernet port of 2631A are in OSPF area 0, ETH0 of 2631B is area 1, ETH0 of 2631C is area 2, and ETH0 of 2631D is area 3. When OSPF works normally, any router in the network can ping any IP address in the network.)
