5. Now that the encapsulation types match on each end of the serial line, ping
from the router prompt of Terminus to Leftist. It should work just fine. You
should see:
terminus#ping 200.200.200.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 200.200.200.2, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/36 ms
Ping from Terminus to Urvile. Initially you may think it should not work so jiffy
spiffy-like because you have PPP as an encapsulation on one serial line and HDLC as
the encapsulation on the other line. But since we have the same encapsulation on
each end of the serial line we can mix and match encapsulations over the entire
network. Geeze. If we could not then the entire Internet would have to run on only
one encapsulation type.
You should see:
terminus#ping 12.0.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.0.0.1, timeout is 2 seconds:!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 64/64/68 ms
