Juniper PPPoE Proceedure

Juniper users a hierarchical configuration and the PPPoE settings fall under the interfaces section. In this example we will be using the fast ethernet port 0/0/1 for the WAN interface and the final configuration will look like:

interfaces {
    fe-0/0/1 {
        unit 0 {
            encapsulation ppp-over-ether;
        }
    }
    pp0 {
        unit 0 {
            ppp-options {
                pap {
                    access-profile ppp-profile;
                    local-password "dkwoxslxqpz";##SECRET-DATA
                    local-name "username";
                    passive;
                }
            }
            pppoe-options {
                underlying-interface fe-0/0/1.0;
                auto-reconnect 10;
                client;
                idle-timeout 0;
            }
            family inet {
                negotiate-address;
                mtu 1492;
            }
        }
    }
}

Below is a walk through on what commands to enter:

You will want to ssh / telnet to the router and be at the CLI (command line interface):

--- JUNOS 11.4xxxx built 2011-05-15 22:21:00 UTC
{master}
user@router>

We will need to be in the edit mode at this point:

user@router>edit

Entering configuration mode
Users currently editing the configuration:
{master}[edit]
user@router#

Now we will want to set the interface FastEthernet 0/0/1 to use PPPoE encapsulation:

user@router#edit interfaces fe-0/0/1 unit 0

{master}[edit interfaces fe-0/0/1 unit 0]
user@router#set encapsulation ppp-over-ether;
user@router#exit

{master}[edit]
user@router#

Next we will want to edit the ppp pap options pp0 interface:

user@router#edit interfaces pp0 unit 0 ppp-options pap

{master}[edit interfaces pp0 unit 0 ppp-options pap]
user@router#set access-profile ppp-profile
user@router#set local-password "xmission password"
user@router#set local-name "xmission username"
user@router#set passive
user@router#exit

{master}
user@router#

Now we will want to configure the pppoe options:

user@router#edit interfaces pp0 unit 0 pppoe-options

{master}[edit interfaces pp0 unit 0 pppoe-options]
user@router#set underlying-interface fe-0/0/1.0
user@router#set auto-reconnect 10
user@router#set client
user@router#set idle-timeout 0
user@router#exit

{master}
user@router#

Last we will want to set the ip address, in this example we will use auto negotiate:

user@router#edit interfaces pp0 unit 0 family-inet

{master}[edit interfaces pp0 unit 0 family-inet]
user@router#set negotiate-address
user@router#set mtu 1492
user@router#exit

{master}
user@router#

Commit these changes and exit edit mode.
