Hola Ernesto,
Puedes por favor mostrarnos la configuracion de Sw2 y R2?
Here is a couple of question that I would ask to myself in order to
troubleshoot the problem..
Do you have R2 in the same subnet as R1?
Do you have the trunk at Sw2 passing the same Vlans ??
Do you have the interface connecting R2 in the Same Vlan as R1?
I am not sure about if this is possible in Dynamips, but to test that you can
create an SVI for that Vlan (3) in the same Address that R1 and R2 are hanging
and try the ping from Sw1 or Sw2
HTH

Subject: Help for trunking with dynamips and IEv4
Hi,
I don't succeed in doing a simple trunk among two SW with dynamips
the trunk works well, but if ping from R1 to R2 no it works
R1-----SW1-----SW2--------R2
Rack1R1#ping 10.0.0.2 repeat 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
..........
Thanks

Do I forget me of something?
