Filter support for service packet counting—You can count service packets, applying
them to a specific named counter (__junos-dyn-service-counter), for use by RADIUS.
To enable service packet accounting, specify the

[Policy Framework, Subscriber Access]
Support for domain maps that apply configuration options based on subscriber
domain names (MX Series and M Series routers)—You use domain maps to apply
access options and session-specific parameters to subscribers whose domain name
corresponds to the domain map name. You can also create a default domain map that
the router uses for subscribers whose username does not include a domain name or
has a non-matching domain name.
Domain maps apply subscriber-related characteristics such as profiles (access,
dynamic, and tunnel), target and AAA logical system mapping, address pool usage,
and PADN routing information.
You configure domain maps at the
hierarchy level.

L2TP LAC support for subscriber management (MX Series routers)—You can now
configure an L2TP access concentrator (LAC) on MPC-equipped MX Series routers.
As part of the new L2TP LAC support, you can configure how the router selects a tunnel
for a PPP subscriber from among a set of available tunnels. The default tunnel selection
method is to fail over between tunnel preference levels. When a PPP user tries to log
in to a domain, the router attempts to connect to a destination in that domain by means
of the associated tunnel with the highest preference level. If the destination is
unreachable, the router then moves to the next lower preference level and repeats the
process. No configuration is required for this tunnel selection method.
You can include the
statement at the
fail-over-within-preference
[edit services l2tp]
hierarchy level to configure tunnel selection failover within a preference level. With this
method, when the router tries to connect to a destination and is unsuccessful, it selects
a new destination at the same preference level. If all destinations at a preference level
are marked as unreachable, the router does not attempt to connect to a destination
at that level. It drops to the next lower preference level to select a destination. If all
destinations at all preference levels are marked as unreachable, the router chooses
the destination that failed first and tries to make a connection. If the connection fails,
the router rejects the PPP user session without attempting to contact the remote
router.
By default, the router uses a round-robin selection process among tunnels at the same
preference level. Include the
statement at the statement at
weighted-load-balancing
the
hierarchy level to specify that the tunnel with the highest weight

within a preference is selected until its maximum sessions limit is reached. Then the
