Rewrite rules are applied accordingly to the forwarding class, packet loss priority (PLP),
and code point. The proper transfer of the inner IP header to the outer IP header of the
L2TP packet depends on the classifier and rewrite rule configurations.
The following table shows how the classifier and rewrite-rule values transfer from the
inner IP header to the outer IP header. The inner IP header (ob001) is classified with
assured-forwarding and low loss priority at the ingress interface. Based on the
assured-forwarding class and low loss priority in the rewrite rule, the outer IP header
is set to ob001 at the egress interface.

L2TP tunnel profiles and AAA support for tunnels in subscriber management (MX
Series routers)—You can configure a set of attributes to define an L2TP tunnel for PPP
subscribers. More than one tunnel can be defined for a tunnel profile. Tunnel profiles
are applied by a domain map before RADIUS authentication. When the RADIUS
Tunnel-Group VSA [26-64] is specified in the RADIUS login, then the RADIUS tunnel
profile (group) overrides a tunnel profile specified by the domain map. The tunnel is
then configured according to RADIUS tunnel attributes and VSAs.
To configure a tunnel profile, include the
hierarchy level. To define a tunnel for a profile, include the
