Configuring a PPPoE Interface (Required)

Navigate to the Interfaces level in the configuration hierarchy.

In the configuration editor hierarchy select Interfaces.

From the top of the configuration hierarchy, enter

edit interfaces

Create a PPPoE interface with a logical interface unit 0.

1. Next to Interface, click Add new entry.
2. In the Interface name box, type pp0 and click OK.
3. Under Interface name, click pp0.
4. Next to Unit, click Add new entry.
5. In the Interface unit number box, type 0.

Enter

edit pp0 unit 0

Configure an ISDN interface as the backup interface for the PPPoE interface—for example, dl0.0.

1. Next to Backup options, click Configure.
2. In the Interface box, type dl0.0.
3. Click OK.

Enter

set backup-options interface dl0.0

Specify the logical Ethernet interface or the logical ATM interface as the underlying interface for the PPPoE session—for example, fe-0/0/1.0 or at-2/0/0.0.

1. Next to Pppoe options, click Edit.
2. In the Underlying Interface box, type the following:

   For the logical Ethernet interface, type fe-0/0/1.0.

   For the logical ATM interface type, at-2/0/0.0.

Enter one of the following:

• For the logical Ethernet interface, type set pppoe-options underlying-interface fe-0/0/1.0.
• For the logical ATM interface, type set pppoe-options underlying-interface at-2/0/0.0.

Identify the access concentrator by a unique name—for example, ispl.com.

In the Access concentrator box type ispl.com.

Enter

set pppoe-options access-concentrator ispl.com

Specify the time in seconds to reconnect after a PPPoE session is terminated—for example, 100 seconds.

In the Auto reconnect box, type 100.

Enter

set pppoe-options auto-reconnect 100

Identify the type of service provided by the access concentrator, such as the name of the Internet service provider (ISP), class, or quality of service—for example, video@ispl.com.

1. In the Service name box, type video@ispl.com.
2. Click OK to apply your entries to the configuration.

Enter

set pppoe-options service-name video@ispl.com

Configure the maximum transmission unit (MTU) of the protocol—for example, 1492.

1. In the Inet box, select Yes and click Configure.
2. In the Mtu box, type 1492.

Enter

up

set pp0 mtu 1492

Configure the PPPoE interface address in one of the following ways:

• Assign source and destination addresses—for example, 192.168.1.1/32 and 192.168.1.2.
• Derive the source address from a specified interface—for example, the loopback interface, lo0.0—and assign a destination address—for example, 192.168.1.2. The specified interface must include a logical unit number and have a configured IP address.
• Obtain an IP address by negotiation with the remote end. This method might require the access concentrator to use a RADIUS authentication server.

Select one of the following IP address configurations:

To assign the source and destination address:

1. Next to Address, click Add new entry.
2. In the Source box, type 192.168.1.1/32.
3. In the Destination box, type 192.168.1.2.
4. Click OK until you return to the Unit page.

To derive the source address and assign the destination address:

1. Next to Unnumbered address, select the Yes check box and click Configure.
2. In the Destination box, type 192.168.1.2.
3. In the Source box, type lo0.0.
4. Click OK until you return to the Unit page.

To obtain an IP address from the remote end:

1. Next to Negotiate address, select the Yes check box.
2. Click OK until you return to the Unit page.

Enter up, then do one of the following:

• To assign the source and destination address, type set pp0.0 family inet address 192.168.1.1/32 destination 192.168.1.2.
• To derive the source address and assign the destination address, type set pp0.0 family inet unnumbered-address lo0.0 destination 192.168.1.2.
• To obtain an IP address from the remote end, type set pp0.0 family inet negotiate-address.

Disable the sending of keepalives on a logical interface—for example, no-keepalives.

1. From the Keepalive choices list, select no keepalives.
2. Click OK to apply your entries to the configuration.

Enter

set pp0.0 no-keepalives
