Re-marking of MVPN GRE encapsulation DCSP at ASBR (MX Series routers
with Trio MPC/MIC interfaces) Enables you to configure DSCP marking for
GRE encapsulated packets that aligns with the service provider core CoS policy
for an MVPN. To configure, include the DSCP

PD-5-10XGE-SFPP, 10-port 10-Gigabit Ethernet (Type 4) PIC (T640, T1600,
and TX Matrix routers with G-FPC4, ST-FPC4, and ST-FPC4.1) Supports a
WAN bandwidth of 100 Gbps in addition to the following features:
Intelligent handling of oversubscribed traffic
Line rate operation on up to five 10-Gigabit Ethernet ports
Tap features, such as flexible encapsulation, source address (SA) MAC
learning, MAC accounting, and MAC policing
Stacked virtual LAN (VLAN) tag and VLAN rewrite functionalities

Intelligent oversubscription services (MX Series with 16-port 10-Gigabit
Ethernet MPC with SFP+) The 16-port 10-Gigabit Ethernet Modular Port
Concentrator (MPC) is an oversubscribed configuration. Consequently, it is
necessary to protect control traffic over best-effort traffic as soon as packets
enter the line card. To do this, packets entering the line card are assigned a
preclassifier control traffic class according to the header types (such as destination
MAC addresses, and Layer 4 ports) in the packet. The preclassifier provides a
good way to classify and queue important control traffic in a different high-priority
queue from that used for best-effort traffic.
The preclassifier (control or best effort) is assigned prior to packets being accepted
into the initial stream and is used by the line card as an early designation (before
any class-of-service configuration is applied). When oversubscription occurs,
control traffic will be queued separately and should not be subject to any dropped
packets.
The Layer 2 protocols supporting the preclassifier are:
