Rip (CISCO) Case 2 of OSPF advanced applications

Rip (CISCO) Case 2 of OSPF advanced applications

Case 2:
1. Job Requirements:
& Lt; 1 implement communication between networks running ospf and rip
Method: Route redistribution and injection default route
& Lt; 2 configure the peripheral area
& Lt; 3 configure the complete peripheral area
2. Topology

3. The device configuration is as follows:

4. Route redistribution:
One-way redistribution cannot be pinged
R4 # ping 192.168.7.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.7.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
(Because OSPF is used in a large network and the traffic is large, the transmitted data cannot be tolerated. Therefore, the default route is injected into rip)
