Trying to understand what is going on (if it is a common behavior).

Access-list applyed to ethernet denying ping from R4 to itself

r4#p 172.16.48.4

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.48.4, timeout is 2 seconds:
*Mar 1 02:28:49.919: %SEC-6-IPACCESSLOGDP: list 101 denied icmp 172.16.48.4 -> 172.16.
48.4 (8/0), .....
Success rate is 0 percent (0/5)

r4#sh run int fa 0/0
