bridging between 2 ATM subinterfaces/PVC's

Discussion in 'Cisco' started by Remco Bressers, Aug 11, 2005.

  1. 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 and on the second router 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,

  2. 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

  3. 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 :(

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