6.7 Configuring MP authentication binding through the
VT
6.7.1 Establishing the configuration task
Applicable environment
To obtain broader bandwidth, you can bind multiple PPP links together into a VT.
The binding authentication includes:
z
User name authentication
z
Endpoint discriminator authentication
z
Username and endpoint discriminator authentication.
Currently, MP does not support binding the interfaces of different boards on a router. You can
only bind MP based on the user name.
When you authenticate the MP binding, the process contains two steps as follows:
z
The bound PPP interface must pass the PAP and CHAP authentication.
z
The authenticated object must find the corresponding VT according to the username. If
no VT corresponds to it, the binding cannot succeed.
