Configuring MLPPP Authentication and Other Attributes

Perform the following optional tasks to configure authentication on interfaces with MLPPP encapsulation or MLPPP bundles.

• Specify one or more PPP authentication types.
• Modify the length of the CHAP challenge.
• Specify the maximum number of retries.

  Note: The JunosE Software PPP application accepts null usernames during PAP and CHAP authentication. When the PPP application receives an authentication request that includes a null username, PPP passes the request to AAA. To take advantage of this feature, configure your authentication server to support the use of null usernames.

The available ppp command options are the same for interfaces whether they are configured with PPP or MLPPP.
