Configuring Static MLPPP

Before You Configure Static MLPPP

Before you begin configuring static MLPPP, you must configure the physical line interfaces to be aggregated by MLPPP. See the following chapters:

• Configuring Channelized T3 Interfaces in JunosE Physical Layer Configuration Guide
• Configuring T3 and E3 Interfaces in JunosE Physical Layer Configuration Guide
• Configuring Channelized OCx/STMx Interfaces in JunosE Physical Layer Configuration Guide

The procedures described in Configuring Static MLPPP and Adding Member Links to a Multilink Bundle assume that a physical line interface has been configured.

Configuring Static MLPPP and Adding Member Links to a Multilink Bundle

Static MLPPP configuration consists of two general tasks, each with several subtasks.

To configure static MLPPP:

1. Create the member links to be aggregated into a multilink bundle.
   1. From Global Configuration mode, specify the individual interface on which you want to configure MLPPP.
      host1(config)#interface serial 2/0:1/1
   2. Specify MLPPP as the encapsulation method on the interface.
      host1(config-if)#encapsulation mlppp
   3. (Optional) Specify the keepalive timeout value for the member link interface.
      host1(config-if)#ppp keepalive 50
   4. (Optional) Specify the authentication method for the member link interface.
      host1(config-if)#ppp authentication pap chap
   5. (Optional) Enable hash-based link selection instead of the default round-robin link selection for the member link interface.
      host1(config-if)#ppp hash-link-selection
2. Add member links to a multilink bundle.
   1. Define the MLPPP bundle.
      host1(config)#interface mlppp group1
   2. Add each member link.
      host1(config-if)#member-interface serial 2/0:1/1
   3. Assign an IP address to the MLPPP bundle.
      host1(config-if)#ip address 10.10.100.1 255.255.255.0
   4. (Optional) Specify the keepalive timeout value for the MLPPP network interface (the entire MLPPP bundle).
      host1(config-if)#ppp keepalive 50
   5. (Optional) Specify the authentication method for the MLPPP network interface (the entire MLPPP bundle).
      host1(config-if)#ppp authentication pap chap
   6. (Optional) Enable hash-based link selection instead of the default round-robin link selection for the MLPPP network interface (the entire MLPPP bundle).
      host1(config-if)#ppp hash-link-selection
