Hi,
This shouldn't be a problem. I've done it before. Just
make sure the native VLAN is the same on each 802.1q
connection (ie: switch port and router port connecting
to each other are in same native VLAN). If you have a
newer router IOS you can do a 'encaps dot1q # native'
command. Older IOS's didn't have the native keyword.
If you don't have the IOS with the native keyword you
can put the native VLAN IP on the main interface which
will be native VLAN.
You might also want to hard-code the trunk to on
instead of auto/desirable and turn channeling off and
hardcode the speed/duplex.
