Access List Troubleshoot :- 

Lets creates one scenario here.

Suppose you forgot to write, permit statement after deny statement.

The traffic which is unclassified will automatically deny.

Lets try to reach from Router R1 to PC-3 and Router R2 to PC-3


R1#ping 192.168.3.30

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.3.30, timeout is 2 seconds:
UUUUU
Success rate is 0 percent (0/5) R2#ping 192.168.3.30

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.3.30, timeout is 2 seconds:
UUUUU
Success rate is 0 percent (0/5)

we are unable to reach from Router R1 to PC-3 and Router R2 to PC-3, because, there is only one deny statement for host- 192.168.1.10, no permit statement are there, so the all traffic treated as unclassified, and unclassified traffic deny automatically.
