Configuring Dynamic MLPPP
ppp multilink enable

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.
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 511.
To configure a profile for dynamic MLPPP:
Create a profile by assigning it a name.
1.
host1(config)#profile dynmlppp
Enable creation of dynamic MLPPP interfaces.
2.
host1(config-profile)#ppp multilink enable
Specify a virtual router to which dynamic IP interfaces created using this profile will
3.
be assigned.
host1(config-profile)#ip virtual-router egypt
Specify an IP loopback interface with which dynamic IP interfaces created using this
4.
profile will be associated.
host1(config-profile)#ip unnumbered loopback 0
(Optional) Set other desired PPP characteristics by using the ppp commands described
5.
in "Configuring Authentication" on page 310 and "Configuring Other PPP Attributes"
on page 312.
Use in a profile to enable the creation of dynamic MLPPP interfaces.
Example
host1(config-profile)#ppp multilink enable
Use the no version to cause the LNS to reject any incoming requests to create dynamic
MLPPP interfaces.
See ppp multilink enable.
