Configuring Applications over ATM 137Note that a PVC cannot carry multiple protocols when the ATM AAL5 isencapsulated with aal5mux. Once IPoA is configured on the PVC, other protocolssuch as IPoEoA, PPPoA and PPPoEoA are not supported.Configuring IPoEoA Follow these steps to enable IPoEoA on PVC:Configuring PPPoA When two routers are connected using DSL interfaces through a dial-upconnection, configure them as PPPoA server and client respectively. The two aredifferent in that, with the PPPoE server, you should configure an address pool toallocate IP address for the remote node; with the PPPoE client, you shouldconfigure address negotiation to accept the IP address allocated by the server end.For relevant information, refer to “PPP and MP Configuration” on page 363The following configurations enable the PVC to carry PPP and configure a PPPmapping for the PVC.Note that a PVC cannot carry multiple protocols when the ATM AAL5 isencapsulated with aal5mux. Once PPPoA is configured on the PVC, otherprotocols such as IPoA, IPoEoA, and PPPoEoA are not supported.Follow these steps to configure PPPoA:To do... Use the command...
