New Features in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
JUNOS subscriber access scaling values (M120, M320, and MX Series
routers) Table 2 on page 28 lists the DHCP, PPP, and PPPoE scaling values
supported for subscriber access in this release of M120, M320, and MX Series
routers. In this table, DPC means only MX Series Enhanced Queuing IP Services
DPCs (DPCE-R-Q-40GE-SFP and DPCE-R-Q-4XGE-XFP). These DPCs support only
DHCP subscribers; they do not support PPP subscribers.

PPP connections (logical interfaces) are supported in a range of configurations.
For example, 63,999 PPP connections per chassis are supported when all
subscribers are configured on the same VLAN. In this case, 63,999 pp0 interfaces
are configured under the same VLAN logical interface and the one remaining
logical interface is consumed for the single VLAN.
At the other extreme, when you configure each subscriber on a separate VLAN
(using stacked VLANs), up to 32,000 PPP connections per chassis are supported.
