Sorry i didn't see the last part about not modifying the router interfaces i dont see how you would do this while 1.) tagging all VLANS including the native and 2.) Not modifying the interfaces on R6
I think you are in a catch 22 here. If requirement #1 was not there you could simply interface FastEthernet0/6 switchport trunk encap dot1q switchport mode trunk switchport trunk allowed vlan 56,76 switchport trunk native vlan 56 On Tue, Feb 22, 2011 at 1:31 PM, Daniel Gheorghe <[email protected]>wrote: > The behavior is the same if the Cat port is dynamic or not.
