Ensure that the host does not route between the VLANs, as this kills your
security policy.

Why not just use dot1q?

No, they are similar products, but IIRC some switches support both products,
so you could use ISL on one trunk, and dot1q on another.
>Please indicate me link where i can find a example of this configuration ?
I would recommend dot1q everywhere.
