Sorry, I did mistake in previuos email.
CORRECTION:
Hi Modular,
I guess you can configure *Cat1* port which is connected with *Cat2* as
dot1q-tunnel with 'l2protocol-tunnel cdp' while port on Cat2 will remain as
trunk port. This would be an asymetric setup and will result in desired
output.
In this specific scenario of 3 devices you don't need to configure Cat2, its
port connected with Cat1 could be in access or trunk mode.
Regards,
Mujeeb
