Experimental steps:
1 Build the topology and connect it
2 Configure the IP addresses of PC1 and PC2 AR1 AR2 AR3 interface ip
Configure the ip of AR2 0/0/0
3 Configure direct routing
Configure AR1 direct route
Configure the interface IP address of AR1
Configure the interface ip of AR3
4 Configure routing
Configure the routing table of AR2
Configure the routing table of AR1
Configure the routing table of AR3
5 Test PC1 ping PC2
The test timed out and checked whether a loop was formed. After checking, it was found that there were only outgoing routes and no return routes. Add a route to PC1 in AR3
PC1 ping PC2 test is successful
Experiment summary:
Disable prompt information: undo info-center enable
View the routing table: display ip routing-table
Set router interface ip: 1) interface GigabitEthernet [interface number]
2) ip address [ip address]
Setting direct route: equivalent to configuring interface ip
Set static routing: ip route-static 192.168.4.0 255.255.255.0 192.168.2.200
