LSA1 Router LSA (Router LSA)

2. Experimental topology

3. Experimental configuration

R1 configuration

Interface Loopback0

Ip address 1.1.1.1 255.255.255.0

Interface Serial0/0

Ip address 12.1.1.1 255.255.255.0

Router ospf 110

Router-id 8.8.8.1

Network 1.1.1.0 0.0.0.255 area 0

Network 12.1.1.0 0.0.0.255 area 0

R2 configuration

Interface Loopback0

Ip address 2.2.2.2 255.255.255.0

Interface Serial0/0

Ip address 12.1.1.2 255.255.255.0

Router ospf 110

Router-id 8.8.8.2

Network 2.2.2.0 0.0.0.255 area 0

Network 12.1.1.0 0.0.0.255 area 0

4. Conclusion verification

Link ID and ADV Router are Router ID.

The advertised content is routing and topology

The above four figures also verify the conclusion that routers in the same area have the same LSDB.
