First Observation, isl works on Fastethernet interfaces i.e 100MB link.
Your posted config below indicates a 10MB interface. You might want to
double-check this again.
Secondly, since all you were trying to do is to bridge traffic between
your VLANs, you need not assign an IP Address to the BVI interface.
Remember that when "irb" is configured, it bridges all traffic by
default, you might want to remove "bridge 1 route ip ". Again, I assume
that you just wanted to bridge your traffic abetween the VLANs and not
route.
Check the port status on the switch to make sure that it is in "connected
state" and negoatiated 100 MG. As trivial as they sound, these might be
the cause of your headache.
Does this info helps?
