host1(config-subif)#interface atm 0/1.20.1
Select PPP as the encapsulation method.
7.
host1(config-subif)#encapsulation ppp
(Optional) Configure maximum transfer unit (MTU) parameters.
8.
host1(config-if)#pppoe mtu 1380
(Optional) Configure an access concentrator (AC) name on the PPPoE interface.
9.
host1(config-subif)#pppoe acname CYM9876
(Optional) Set up the router to prevent a client from establishing more than one
10.
session using the same MAC address.
When the duplicate protection feature is enabled, multiple IWF PPPoE sessions that
contain the same MAC address are still processed and can access network services
until the maximum number of PPPoE sessions configured per major interface
(configured using the pppoe sessions command) is reached. For more information
about how IWF PPPoE sessions with duplicate addresses are handled, see "Processing
of IWF PPPoE Sessions with Duplicate MAC Addresses" on page 391.
host1(config-subif)#pppoe duplicate-protection
Assign an IP address and subnet mask to the PVC.
11.
host1(config-subif)#ip address 192.32.10.20 255.255.255.0
(Optional) Configure additional PPPoE subinterfaces by completing Steps 6 through
12.
11 using unique numbering.
host1(config-subif)#interface atm 0/1.20.2
Use to override the current PPPoE maximum session value set with the pppoe sessions
command with the PPPoE maximum session value returned by the RADIUS server in
the Max-Clients-Per-Interface VSA [26-143].
RADIUS returns the Max-Clients-Per-Interface VSA value in Access-Accept messages
for each subscriber during PPP authentication.
By default, the router ignores the PPPoE maximum session value returned by RADIUS.
The router never overrides the maximum number of PPPoE subinterfaces supported
per line module with a value from RADIUS that is either 0 (zero) or greater than the
maximum number of supported PPPoE subinterfaces. For example, if the maximum
number of PPPoE subinterfaces supported for a particular line module is 8000 and
the PPPoE maximum session value returned by RADIUS is 0 (zero) or greater than
8000, the RADIUS value in this case is ignored.
See JunosE Release Notes, Appendix A, System Maximums corresponding to your
software release for information about the maximum number of PPPoE subinterfaces
supported for each line module.
