Hi group,
I am scratching my head on this one (probably something basic), please
help! And thanks in advance....
R3(f0/1)---------(f0/4)CAT1(f0/14)-----------(f0/14)CAT2(f0/5)----------
-----R4(f0/0)
When I ping from R3 to R4, I get encapsulation failed message on R3:
R3(config-if)#do ping 172.16.34.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.34.4, timeout is 2 seconds:
