Description

This article provides an example of the Point-to-Point over ATM (PPPoA) configuration.

Solution

Configuration for the at-1/0/0 interface: 

at-1/0/0 { 
		description ADSL; 
		encapsulation atm-pvc; 
		atm-options { 
			vpi [vpi number]; 
		} 
		dsl-options { 
			operating-mode auto; 
		} 
		unit 0 { 
			description PPPoA; 
			encapsulation atm-ppp-vc-mux; 
			vci ([vpi number].[vci number]); 
			ppp-options {
				chap {
					access-profile (access-profile-name);
					passive;
				} 
				pap {
					default-password (password provided by the service-provider); 
					local-name (user-id provided by the service-provider); 
					local-password (password provided by the service-provider); 
					passive; 
				}
			}
			family inet {
				address (static IP provided by the service-provider);
			}
		}
    }

Access configuration for chap: 

    access {
		profile (access-profile-name){
			client (user-id provided by the service-provider) 
chap-secret (password provided by the service-provider);
		}
	}

Binding the at-1/0/0 interface to a zone: 

    security-zone untrust {
         host-inbound-traffic {
            system-services {
                all; 
            } 
			protocols {
				all;
			}
        }
		interfaces { 
			at-1/0/0.0;
		}
    }

Configure the default-route: 

    user@host# show routing-options static {
		route 0.0.0.0/0 next-hop at-1/0/0.0;
    }

Corresponding set of commands for the configuration: 

set interfaces at-1/0/0 description ADSL
set interfaces at-1/0/0 encapsulation atm-pvc
set interfaces at-1/0/0 atm-options vpi [vpi number]
set interfaces at-1/0/0 dsl-options operating-mode auto

set security zones security-zone untrust interfaces at-1/0/0.0 host-inbound-traffic system-services all
set security zones security-zone untrust interfaces at-1/0/0.0 host-inbound-traffic protocols all
set access profile (access-profile-name) client (user-id provided by the service-provider) chap-secret (password provided by the service-provider)
