Configuring Single PPP Clients per ATM Subinterface

Figure 1 shows a conceptual view of the configuration of a single PPP client per ATM subinterface.

Configure an ATM interface by entering Configuration mode and performing the following tasks. For more information about configuring ATM interfaces, see JunosE Link Layer Configuration Guide.

1. Configure a physical interface.
   host1(config)#interface atm 0/1
2. Configure the subinterface.
   host1(config-if)#interface atm 0/1.20
3. Configure a permanent virtual circuit (PVC) by specifying the vcd (virtual circuit descriptor), the vci (virtual channel identifier), the vpi (virtual path identifier), and the encapsulation type.
   host1(config-if)#atm pvc 10 22 100 aal5snap
4. Configure PPP encapsulation.
   host1(config-if)#encapsulation ppp
5. Configure PAP or CHAP authentication.
   host1((config-if))#ppp authentication chap
6. Assign a profile to the PPP interface.
   host1(config-subif)#profile foo
