Below is the output of the show ip route command as run on the 2501C
router.

Now all the routers have the correct routing table, and all the routers and
hosts should be able to communicate without a problem. However, if you
add even one more route or another router to the internetwork, you will
have to update all routers’ routing tables by hand. This is fine for a small network,
but it is too time-consuming a task for a large internetwork.
Verifying Your Configuration
Once all the routers’ routing tables are configured, they need to be verified.
The best way to do this is with the Ping program. By pinging from routers
2621A and 2501C, the whole internetwork will be tested end-to-end.
Here is the output of a Ping to network 172.16.50.0 from the 2621A
router:
2621A#ping 172.16.50.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.50.1, timeout is
