Next, you use the show ip route command on Router B to verify the existence of a return
route to the translated address.
From the results in Example 7-7, you discover that Router B has no route to the translated
network address of 172.16.0.0.

You return to Router A and enter the show ip protocol command to determine if Router A
is advertising the translated address of 172.16.0.0, as demonstrated in Example 7-8.
You ?¬?nd that Router A is advertising 192.168.1.0, which is the network that is being
translated, instead of advertising network 172.16.0.0, which is the network to which the
addresses are being translated.
