Thanks for the response. Ive verified what you mentioned. The gateway
setting is one of the requirements but for now I cant ping SW2 which is the
gateway so it wont do me any good. I love Dynamips but sometimes Im not
sure if its a config problem or a Dynamips bug.

Ip routing doesn't need to be enabled. You need to use the ip
default-gateway for the 2 client switches pointing to the main Switch and
make sure the SVI's are created on all 3 switches. Also make sure your
trunking is working and just ping it should work. Maybe post your config to
have a look if that doesn't work.

Hi,
The lab scenario I have is three switches, each with their own vlan 255
interface. All other VLANs are working that have routers plugged into
access ports. I see VLAN 255 as active on each switch and it shows up on
the trunks but there the local VLAN 255 interface cannot ping any of the
other switch s VLAN 255 interfaces. ARP requests fail. Can anyone tell me
what I m doing wrong?
Thanks,
Matt
