I found the same problem a couple a weeks ago. Then I found that vlan
trunking with 802.1q is qorking propertly from IOS 12.0/12.1. I tried
the new release and everything was quite ok...

Take a look

Hello there,
I've been playing around with some VLAN stuff lately
and have seen some odd behavior with trunking and I
can't find a answer so thought I'd see if anyone here
knew, because it is bugging me.
Real basic setup.
Cisco router with FE connecting to a switch. VLANs 1,
2, and 3. Workstation on switch in VLAN 2 and VLAN 3.
Dot1Q trunk with all VLANs defined. Sub-interfaces on
router for dot1q. Ping from PC in VLAN2 to VLAN3 and
don't get further then router interface for that VLAN.
Change to ISL encaps and everything works fine. Change
back to Dot1Q and things continue to work. Save
configs and reload switch and routers and things
continue to work.
I also had a similar thing when I didn't configure a
VLAN1 sub-interface on the router (just 2 and 3). Once
I added VLAN1 thing started working. Took VLAN1 away
for kicks and things still worked. Weird.
Any one have any thoughts???
Thanks, Erick
