Hi Brian,
first question
--------------------
When you have irb configured and you need to configure hsrp, then that
should be configure in BVI in intreface or
the ethernet interface ????. The ethernat inter face does not configure
with ip address.
second question
-------------------------
there are two sub interface in fa0/0 and each interface are in different vlan.
Now you want to configure dlsw between these vlan and a token ring or a
vlan in other router.
do i need to configure two diffrent dlsw bridge group or only one bridge group.
Thanks,
Beda
