• Binding physical interfaces to the VT interface by using the ppp mp virtual-template command. In

this case, the configuration of authentication is optional. If the authentication is not configured, the

system binds links according to the descriptor of the peer end. If the authentication is configured,

the system binds links according to the username, the descriptor of the peer, or both.

• Associating a username to the virtual template. After a user passes the authentication, the system

searches for the VT interface associated to the username and bundles links according to the

username and the descriptor of the peer. To ensure a successful link negotiation, configure the ppp

mp command and two-way authentication (PAP, CHAP, MS-CHAP, or MS-CHAP-V2) on the

bundled interfaces.

Configuration restrictions and guidelines

• The ppp mp command and the ppp mp virtual-template command are mutually exclusive on an

interface.

• You must configure the interfaces to be bundled in the same way.

• In actual use, you can configure one-way authentication, where one end associates physical

interfaces to a VT interface and the other end searches for the VT interface by username.

• A VT interface is intended to provide only one service, such as MP, L2TP, or PPPoE.
