Hi,

On a Cisco 7204VXR i want to configure 2 ATM PVC's, bridged together so they can
communicate transparently.
On the 7204 i configured the interfaces as follows :

int atm1/0.162055 point-to-point
pvc 16/2055
encap aal5snap
bridge-group 1

int atm1/0.162056 point-to-point
pvc 16/2056
encap aal5snap
bridge-group 1

The bridge group is configured easily like this :

bridge 1 protocol ieee


According to my theory, the two PVC's should be in bridging mode now. The PVC's
are terminated (through a 3rd party network) on DSL routers, where i
configured RFC1483, LLC based. On router 1 i configured IP address 10.0.0.1/24
and on the second router 10.0.0.2/24. They don't seem to 'see'
eachother in any way and i cannot ping from router 1 to router 2.

Can anyone put me in the right direction?

Thanks in advance,

Remco Bressers

You might need to bridge your IP protocol as well. try add "atm route-
bridge ip" to the interfaces or "bridge 1 route ip" to your global
config.

Isn't it the case that i'm using IRB, and 'atm route-bridge ip' is used for RBE
or am i totally wrong?
Second.. The term bridge 1 route ip is also not working :(

No i havent, because the router should do routing, except for these two
subinterfaces.
