Fast-Switched Transparent Bridging over ATM Example (Cisco 7000)

The following configuration example enables fast-switched transparent bridging over ATM:

interface atm 4/0

ip address 1.1.1.1 255.0.0.0 atm pvc 1 1 1 aal5snap

atm pvc 2 2 2 aal5snap atm pvc 3 3 3 aal5snap bridge-group 1

Transparent Bridging over DDR Examples

The following two examples differ only in the packets that cause calls to be placed. The first example specifies by protocol (any bridge packet is permitted to cause a call to be made); the second example allows a finer granularity by specifying the Ethernet type codes of bridge packets.

The first example configures the serial 1 interface for DDR bridging. Any bridge packet is permitted to cause a call to be placed.

The second example also configures the serial 1 interface for DDR bridging. However, this example includes an access-listcommand that specifies the Ethernet type codes that can cause calls to be placed and a dialer list protocol list command that refers to the specified access list.
