Configuring MP

The device does not support MP binding for interfaces on different SPUs.
You can configure MP by using virtual template (VT) or MP-group interfaces:
VT interfaces—VT interfaces are used to configure VA interfaces. After binding multiple PPP links
•
into an MP link, you must create a VA interface for the MP link to exchange data with the peers.
VT interfaces support authentication. The device finds a VT interface for a peer according to the
username provided by the peer. The device then creates a bundle that corresponds to an MP link
based on the VT settings.
MP can create multiple bundles using the same VT interface. Each bundle is an MP link. From the
perspective of the network layer, these links form a point-to-multipoint topology.
The system uses usernames or terminal descriptors to distinguish multiple MP links under one VT
interface. The following binding modes are available:
authentication—Binds links by using authentication usernames. Each authentication username
corresponds to one bundle. The username is sent by the peer to the authenticator in PAP, CHAP,
MS-CHAP, or MS-CHAP-V2 authentication.
descriptor—Binds links by using descriptors. Each descriptor corresponds to one bundle. A
descriptor is received from the peer during LCP negotiation and uniquely identifies the peer.
both—Binds links by using both the authentication username and descriptor.
MP-group interfaces—MP-group interfaces are intended only for MP. On an MP-group interface,
•
only one bundle is allowed, and links cannot be bundled according to the peer descriptor.
Compared with VT interfaces, the configuration of MP-group interfaces is more efficient and easier
to configure and understand.
