DSL Access Architectures and Protocols 191

Step 2

Create an ATM subinterface and PVC:

interface atm

slot

/0.

subinterface-number

{multipoint | point-to-point}

pvc [

name

]

vpi/vci

Step 3 Conﬁgure PPPoA encapsulation, and associate a virtual template with it:

encapsulation aal5mux ppp virtual-template

number

aal5mux encapsulation is used for the PPPoA conﬁguration. virtual-template

serves as the template, and the virtual-access interface is cloned from the

virtual template.

Step 4 Create a virtual template interface:

interface virtual-template

number

Step 5 Conserve IP addresses by conﬁguring the ATM subinterface as unnumbered,

and assign the IP address of the interface type you want to leverage:

ip unnumbered

interface-name-number

Step 6 Create the local IP address pool:

ip local pool

name begin-ip-address-range

[

end-ip-address-range

]

Step 7 Specify the pool for the interface to use:

peer default ip address pool

poolname

Step 8 Enable CHAP or PAP authentication on the interface:

ppp authentication {chap | pap | chap pap | pap chap} [if-needed]

{default |

list-name

} [callin]

Example 8-11 demonstrates the PPPoA conﬁguration of the Cisco 6400 NRP.
