Hi,
I tried that. it is working with two ethernet interfaces, but not at
suninterfaces. look ...
bridge irb
bridge 1 protocol ieee
bridge 1 route ip ------------- for bvi to outside ----------------
int eth 0.1
encapsulation isl 10
bridge-group 1
int eth 0.2
encapsulation isl 20
bridge-group 1
int bvi 1
ip add 1.1.1.1 255.255.255.0
think
ip address of router 1 on vlan 10 ------ 1.1.1.2 /24
ip address of router 2 on vlan 20 ------ 1.1.1.3 /24
1.1.1.1 can go 1.1.1.2 and 1.1.1.3 but 1.1.1.2 can't to 1.1.1.3.....
otherside routers who is coming to 1.1.1.1 can go to the .2 and .3

Umit,
Using "irb" should do the magic. If your router interface is a
fastethernet interface, create a subinterface for each VLAN by using
"encapsulation isl <vlan#" and assgne each subinterface to the same
bridge group. Configure irb, depending on what other things you are
trying to do, you do not necessarily have to assign an IP address to the
BVI interface. Try this, it should work. If you still have problem, how
about pasting your configs online here.
