138 CHAPTER 5: ATM CONFIGURATIONn As for the next hop and the outbound interface, only the former is required whenyou configure a static route on a virtual-template interface. If you want to specifythe outbound interface as well, make sure the physical interface bound to thevirtual-template is valid.Configuring PPPoEoA PPPoE adopts the Client/Server model. It encapsulates PPP packets into Ethernetframes and provides point-to-point connection on Ethernet. The followingconfigurations enable the PVC to carry PPPoE and configure a PPPoE mapping forthe PVC.Note that a PVC cannot carry multiple protocols when the ATM AAL5 isencapsulated with aal5mux. Once PPPoEoA is configured on the PVC, otherprotocols such as IPoA, IPoEoA and PPPoA are not supported.Follow these steps to configure PPPoEoA:Set the PPP authentication modeand IP address; with the PPPoEserver, an address pool shouldbe configured to allocate IPaddress for the peer end; withthe PPPoE client, addressnegotiation should beconfigured to accept the IPaddress allocated by the serverendRefer to “PPP and MPConfiguration” on page363.RequiredQuit to system view quit -Enter ATM interface view interface atm{ interface-number |interface-number.subnumber }-Create PVC, and enter PVC view pvc { pvc-name [ vpi/vci ] |vpi/vci }RequiredConfigure PPPoA mapping forthe PVCmap pppvirtual-templatevt-numberRequiredTo do...
