Configure the PPPoE Family for an Underlying Interface

Describes the PPPoE encapsulation and its limitations. This topic also describes the introduction of "family PPPoE" that can support other protocol families like IPv4 and IPv6 to coexist on the underlying interface.

Use PPPoE encapsulation on the physical interface to dedicate the interface to PPPoE. PPPoE does not support other protocol families on that interface. Configuring IPv4 with PPPoE and IPv6 on the same interface can create protocol conflicts and operational complexities. To address these issues, configure a new PPPoE family such as IPv4 or IPv6. This approach simplifies operations and resolves conflicts.

You can have the PPPoE family configuration on ge, xe, and reth interfaces only. Also, you cannot configure an interface with both “encapsulation ppp-over-ether” and “family pppoe”.

Benefits

The PPPoE configuration supports IPv4 traffic over PPPoE and IPv6 traffic over Ethernet without PPPoE on the same interface. This configuration eliminates separate interfaces, simplifying network architecture and management.

Configuration

To configure the PPPoE family over an underlying interface, use the following command:

Sample Configuration

When you already have ppp-over-ethernet encapsulation configuration, you can't just replace with family pppoe.

For example, the following configuration shows a PPPoE with encapsulation:

To add PPPoE family configuration, you need to:

1. delete interface ge-0/0/11

2. delete interface pp0

3. commit

Add the PPPoE family configuration once the commit is complete. Note that you need to add pp0 configuration as well.
