Link Layer ProtocolBy default, the router performs MP binding according to both username and endpoint.Here the username refers to the received remote username when PPP link performsPAP or CHAP authentication. Endpoint is the unique mark of a router and refers to thereceived remote endpoint when performing LCP negotiation. The system canimplement MP binding according to the received username or endpoint and bind theinterfaces together that have the same username or endpoint.For related commands, see ppp mp user.Example# Perform MP binding according to username.[3Com]ppp mp binding-mode authentication1.1.11 ppp mp interfaceSyntaxppp mp interface virtual-template interface-numberundo ppp mp interfaceViewInterface viewParameterinterface-number: The number of Virtual template interface.DescriptionUsing the ppp mp interface command, you can bind the interface to a specified VirtualTemplate. Using the undo ppp mp interface command, you can cancel the interface’sbinding to a virtual template interface.By default, no interface is bound with the virtual template.After this command is configured, the system will not check the username and endpointwhen performing MP binding, namely, the commands ppp mp bundle-name and pppmp user will not take effect.For related commands, see ppp mp.Example# Bind interface Serial0 to virtual template 1.[3Com-Serial0]ppp mp interface virtual-template 115
