endpoint descriptor. To ensure a successful link negotiation, you must configure
the ppp mp command and two-way authentication (CHAP or PAP) on the
bundled interfaces.
Note:
When the ppp mp virtual-template command is configured on an interface, the
system does not look for a virtual template by username. Instead, it looks for the
template configured by the command.
You must configure the to-be-bundled interfaces in the same way.
In practice, you may configure one-way authentication, where one end associates
physical interfaces to a virtual template interface and the other end searches for
the virtual template interface by username.
A virtual template interface is preferred to provide only one service, such as MP,
L2TP, or PPPoE.
1) Assign physical interfaces to the virtual template
Perform the following configuration in interface view.
Table 1-19 Assign the physical interface to the specified virtual template
Assign the interface to the specified
virtual template
Disable MP bundling on the interface
The configuration of PPP authentication on the physical interface is optional; it is
irrelevant to MP connection setup.
2) Associate a username with the virtual template interface
Perform the following configuration in system view.
Table 1-20 Associate a username with the specified virtual template interface
Associate an MP username with the
specified virtual template interface
Remove the binding
In this approach to MP, the system searches for a virtual template interface by
username. Therefore, to set up an MP connection, you must configure two-way PPP
authentication on the involved physical interfaces. For more information about PPP
