    Example: Configuring Fragmentation and Reassembly for Dynamic MLPPP Over PPPOE

    This example shows you how to configure fragmentation and reassembly for dynamic MLPPP over PPPoE.

    Requirements

    Before you begin configuring static MLPPP, you must configure the individual interfaces on which you want to enable MLPPP. See the following:

    • 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

    Overview

    To configure fragmentation and reassembly for dynamic MLPPP interface you must first enable the creation of a dynamic profile using the ppp dynamic enable command. The ppp fragmentation and ppp reassembly commands then enable fragmentation and reassembly for the dynamic MLPPPP interface.

    Configuring Fragmentation and Reassembly for Dynamic MLPPP Interface over PPPoE

    Step-by-Step Procedure

    The following example configures MLPPP fragmentation and reassembly for a dynamic MLPPP interface over dynamic PPPoE over an ATM 1483 subinterface.

    1. From Global Configuration mode, create a profile by assigning it a name, and access Profile Configuration mode.
      host1(config)#profile dynmlppp2
    2. Enable creation of dynamic MLPPP interfaces and enable fragmentation and reassembly on the link interface.
      host1(config-profile)#ppp multilink enable host1(config-profile)#ppp fragmentation 128 host1(config-profile)#ppp reassembly 1800
    3. (Optional) Specify a virtual router to which dynamic IP interfaces created with this profile will be assigned.
      host1(config-profile)#ip virtual-router westford
    4. (Optional) Specify an IP loopback interface with which dynamic IP interfaces created with this profile will be associated.
      host1(config-profile)#ip unnumbered loopback 1
    5. (Optional) Set other PPP and PPPoE characteristics.
      host1(config-profile)#pppoe sessions 9 host1(config-profile)#ppp authentication chap host1(config-profile)#exit
    6. Configure dynamic MLPPP link interface.
      host1(config)#interface atm 4/0 host1(config-if)#interface atm 4/0.1 host1(config-subif)#atm pvc 52 0 52 aal5autoconfig 0 0 0 host1(config-subif)#profile pppoe dynmlppp2 host1(config-subif)#auto-configure pppoe
