Chapter 4 Configuring PPP over ATM with NAT Configure the ATM WAN Interface Configure the ATM WAN Interface Perform these steps to configure the ATM interface, beginning in global configuration mode. Step 1 Step 2 Step 3 Command interface type number Example: Router(config)# interface atm 0 Router(config-if)# pvc vpi/vci Example: Router(config-if)# pvc 8/35 Router(config-if-atm-vc)# encapsulation {aal5auto | aal5autoppp virtual-template number [group group-name] | aal5ciscoppp virtual-template number | aal5mux protocol | aal5nlpid | aal5snap} Example: Router(config-if-atm-vc)# encapsulation aal5mux ppp dialer Router(config-if-atm-vc)# Purpose Enters interface configuration mode for the ATM interface (labeled ADSLoPOTS or G.SHDSL on the back of your router). Note This interface was initially configured during basic router configuration. See the "Configure WAN Interfaces" section on page 1-6. Creates an ATM PVC for each end node (up to ten) with which the router communicates. Enters ATM virtual circuit configuration mode. When a PVC is defined, AAL5SNAP encapsulation is defined by default. Use the encapsulation command to change this, as shown in Step 3. The VPI and VCI arguments cannot be simultaneously specified as zero; if one is 0, the other cannot be 0. For details about this command and additional parameters that can be set, see the Cisco IOS Wide-Area Networking Command Reference. Specifies the encapsulation type for the PVC and points back to the dialer interface. For details about this command and additional parameters that can be set, see the Cisco IOS Wide-Area Networking Command Reference. Step 4 dialer pool-member number Example: Router(config-if-atm-vc)# dialer pool-member 1 Router(config-if-atm-vc)# Specifies the ATM interface as a member of a dialer profile dialing pool. The pool number must be in the range of 1-255. OL-5332-01 Cisco 850 Series and Cisco 870 Series Access Routers Software Configuration Guide 4-5
