Configuring Dynamic Mlppp - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

Configuring Dynamic MLPPP

You can define a profile to dynamically create MLPPP bundles over L2TP on the LNS.
The profile consists of commands to define the bundle attributes, just as you would
for static configuration. For more information about profiles for dynamic interfaces,
see "Configuring Dynamic Interfaces" on page 465.
To configure a profile for dynamic MLPPP:
1.
2.
3.
Use to terminate an MLPPP session.
If you use the ip or osi keyword, disables the Internet Protocol Control Protocol
(IPCP) or OSI Network Layer Control Protocol (OSINLCP) service for the MLPPP
network interface (MLPPP bundle). Issue only in the context of a network
interface.
If no keywords are issued, issuing this command has the following effect:
If issued in the context of an individual interface, the command affects only
that interface. The ip and osi keywords are not functional in this context.
If issued in the context of an MLPPP bundle, the command affects all MLPPP
link interfaces that are member links of that bundle. The ip and osi keywords
are functional only in this context.
The ppp shutdown command administratively disables the interface.
Example
host1(config-if)#ppp shutdown
If you issue the ppp shutdown command in the context of an MLPPP bundle,
you cannot bring up an individual member link by subsequently issuing the no
ppp shutdown command in the context of that member. You can bring up only
the entire bundle; to do so, you must issue the no ppp shutdown command in
the context of the bundle. If you add new member links while a bundle is shut
down, those new members are also in the shut-down state until the entire bundle
is brought up.
Use the no version to restart a disabled session.
See ppp shutdown.
Create a profile by assigning it a name.
host1(config)#profile dynmlppp
Enable creation of dynamic MLPPP interfaces.
host1(config-profile)#ppp multilink enable
Specify a virtual router to which dynamic IP interfaces created using this profile
will be assigned.
host1(config-profile)#ip virtual-router egypt
