Introduction
When configuring MP via VT interface, you can do one of the following:
Assign physical interfaces to the virtual template using the ppp mp
■
virtual-template command. In this case, the configuration of authentication
is optional. Without authentication, the system binds links according to the
remote endpoint descriptor. With authentication, the system bundles links
according to both remote username and endpoint descriptor.
Associate a username with the virtual template. When bundling links, the
■
system searches for the associated virtual template interface according to the
provided valid username and bundles links according to the username and the
remote 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.
n
When the ppp mp virtual-template command is configured on an interface,
■
the system does not look for a VT interface by username. Instead, it looks for
the template configured by the command.
You must configure the interfaces to be bundled 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.
When configuring MP on the virtual template interface, you can use either
username or endpoint descriptor or both. The username discussed here refers to
the remote username received during PAP or CHAP authentication performed
when setting up a PPP connection. An endpoint descriptor, which uniquely
identifies a device, refers to the remote endpoint descriptor received during LCP
negotiation. The system distinguishes among the MP bundles on a virtual template
interface by username and endpoint descriptor.
