[c-nsp] dot1q question

[Frank Kempermann]

I currently have a Cisco 7204 connected with a Catalyst 2924 per trunk. On
another port of the 2924 a 100FETH WAN route is connected. This secondary
location is connected through a trunk and a VLAN (ISL).

I now wanted to exchange the Catalyst 2924 with a 2950, which supports dot1q
only. Besides that the FETH trunk should be exchanged with a GETH trunk in
the 7204.

I tried out many possibilities; using the following ISL-setup with a
7204FETH and a 2924 everything runs fine, but using dot1q it doesn't work,
where could be my error? I cannot reach the respective IP's from the 7204 to
the 3550, which is working when using ISL.

Do I have to do something with the VTP of the two switches? When using ISL
this doesn't matter. Is something missing in the configuration?

I planned the following:

C7204 i/o GE ---trunk---2950GETH----WAN-FETH(Trunk)----C3550-LAN-FETH
