Dynamic routing protocol OSPF advanced configuration
Route Redistribution Configuration
A route redistribution configuration commands:
Router(config-router)#redistribute protocol metric metric-value metric-type type-value subnetsSecond re-routing distributed configuration example:
RIP and OSPF protocol agreement
router rip //在rip协议中注入ospf协议
redistribute ospf metric 10 //metric为度量值，这里标准为跳数
router ospf 1 //在ospf协议中注入rip协议
redistribute rip metric 200 subnets //度量值为带宽
OSPF redistribution of static routes
router ospf 1
redistribute static metric 100 subnets metric-type2OSPF default route redistribution
router ospf 1

ip route 0.0.0.0 0.0.0.0 10.0.1.1Establishment of experimental topology and complete the advance preparation
Test environment preparation: GNS3 6 router, four PC,
Open GNS3
1, to complete the connection between the topology of FIG route (note: R3 right click and select routes need configure, add two NM-1FE-TX Slots in the working board.)
2, the route R6 cloud cloud modify the icon style pattern, where the route R6 analog mobile ISP.
3, the respective device is connected and turned on.
The official start of the experiment
Step: configure the routing device according to the port topology

The above is all routes of the setup process. Here if we set up an IP address for the PC, you can complete the whole network interoperability.
Step two: Add the IP for the PC
Embodiment the steps of:
PC1
PC1>
PC1> ip 192.168.20.3 192.168.20.1
Checking for duplicate address...
PC1 : 192.168.20.3 255.255.255.0 gateway 192.168.20.1
PC1> PC2
PC2>
PC2> ip 192.168.10.10 192.168.10.1
Checking for duplicate address...
PC1 : 192.168.10.10 255.255.255.0 gateway 192.168.10.1
PC2> PC3
PC3>
PC3> ip 192.168.40.10 192.168.40.1
Checking for duplicate address...
PC1 : 192.168.40.10 255.255.255.0 gateway 192.168.40.1
PC3> No. 4 PC machine
4号PC机>
4号PC机> ip 192.168.30.10 192.168.30.1
Checking for duplicate address...
PC1 : 192.168.30.10 255.255.255.0 gateway 192.168.30.1
4号PC> Step 3: Check each learning dynamic routing
View command: Rn (n = 2 ~ 5) #show ip route
Note: Only run dynamic routing protocols available for learning! ! Thus, R1, and R6 two routes in the routing table is not possible to include other network segments
Step 4: Check the whole network interoperability
Check command (PC machine): ping IP address
