■ New 20-port Gigabit Ethernet MIC with SFP (model number
MIC-3D-20GE-SFP)—Supported on MX Series routers. For a list of supported
MPCs, see the MX Series Line Card Guide.
■ New Modular Port Concentrators (MPCs) and Modular Interface Cards
(MICs)—Supported on MX Series platforms. Up to two MICs plug into the MPC
to provide the physical interface for the MPC line card. The MPCs provide
increased capacity on Gigabit Ethernet and 10-Gigabit Ethernet hardware. For a
list of supported MPCs and MICs, see the MX Series Line Card Guide.

■ New 4-port 10-Gigabit Ethernet MIC with XFP (model number
MIC-3D-4XGE-XFP)—Supported on MX Series routers. For a list of supported
MPCs, see the MX Series Line Card Guide.
■ Layer 2 VPLS, IRB, and mesh group feature parity (MX Series routers with
Trio MPC/MIC interfaces)—Support for Layer 2 feature parity with JUNOS Release
9.1 on MX Series routers that include Trio Modular Port Concentrators (MPCs)
and Modular Interface Cards (MICs).
Layer 2 feature parity includes:
■ Layer 2 bridging
■ VPLS forwarding
■ MAC address learning, aging, and MAC address limit
■ Mesh group support
■ Implicit VLAN mapping
■ Integrated routing and bridging (IRB)
■ Multicast over IRB
■ MAC statistics
Layer 2 features that are not supported in this release include:
■ Spanning Tree Protocols (xSTP)
■ VLAN Spanning Tree Protocol (VSTP)
■ Multiple Spanning Tree Protocol (MSTP)
■ Rapid Spanning Tree Protocol (RSTP)
■ Layer 2 Tunneling Protocol (L2TP)
■ Upgrading a T1600 router to be the LCC0 of the TX Matrix Plus platform—You
can now upgrade an operational T1600 router to be the lcc0 in a newly configured
TX Matrix Plus platform. The procedures require JUNOS Release 10.1 on the TX
Matrix Plus router and the T1600 router. Reboot is required to transfer control
of the T1600 router to the routing matrix. You can also downgrade the lcc0 to
a standalone T1600 router by rolling back to the former configuration. Upgrade
and integration of subsequent operational T1600 routers to form lcc1 and lcc2
