Re: INE ICMP issues on Ethernet Link using dynamips

Vincent,

I am able to ping from SW1 to R3 and in the reverse direction;

Rack1R3#ping 155.1.37.7

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 155.1.37.7, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/136/632 ms
Rack1R3#
term_serv#7
[Resuming connection 7 to SW1 ... ]

Rack1SW1#ping 155.1.37.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 155.1.37.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/17/24 ms
Rack1SW1#sh ver
Cisco IOS Software, 3700 Software (C3725-ADVENTERPRISEK9-M), Version
12.4(15)T10, RELEASE SOFTWARE (fc3)

It appears that you have a dynamips problem.Restarting dynamips may resolve
your issue and my case, I had to
change interface type ( in .net file) on several occasions for the setup to
work.

Thanks

It is said that if you know your enemies and know yourself, you will not be
imperiled in a hundred battles; if you do not know your enemies but do know
yourself, you will win one and lose one; if you do not know your enemies nor
yourself, you will be imperiled in every single battle.
