Setting up the experimental environment in accordance with the experimental lab topology and addressing,
Test connectivity
Two PC ping it, found it impossible to communicate
Look at the routing table:
R1 can be seen in the routing table, no routing information on the network segment where the PC2
Similarly, there is no network routing information about PC1 and PC2 are located on the R2
No routing information on the network segment where the R3 PC1
That is in the initial state, each with its own router only routing information directly connected network segment.
Now across several network segments between PC1 and PC2, to ping the need to configure the routing information on the three routers.
It can be achieved by configuring static routes.
In R1 needs additional information of the network segment 10.0.20.0
See R2 routing table, need to include the next hop destination network segment 20
Look R3 routing table, there are 20 segments, but ping can come, go back but can not find 192.168.10.0 segment Yeah,
The same procedure, again get another on R2:
Completed, successfully ping the
