MPC3E on MX Series Routers Overview

In Junos OS Release 12.2 and later, MX960, MX480, and MX240 routers support the MPC3E (MX-MPC3E-3D) with two MIC slots. The MPC provides the connection between the customer’s Ethernet interfaces and the routing fabric of the MX Series chassis. The MPC is inserted into a MIC slot in an MX series router. MICs provide the physical interface and are installed into the MPCs.

• 100-Gigabit Ethernet MIC with CFP (model number MIC3-3D-1X100GE-CFP)
• 100-Gigabit Ethernet MIC with CXP (model number MIC3-3D-1X100GE-CXP)
• 2-port 40-Gigabit Ethernet MIC with QSFP+ (model number MIC3-3D-2X40GE-QSFPP)

The MPC3E also supports these legacy MICs:

• 20-port Gigabit Ethernet MIC with SFP (model number MIC-3D-20GE-SFP)
• 2-port 10-Gigabit Ethernet MICs with XFP (model number MIC-3D-2XGE-XFP)

The MPC3E requires the Enhanced MX Switch Control Board (SCB) for fabric redundancy. You can also continue to use existing SCBs without fabric redundancy. The MPC interoperates with existing MX Series line cards, including Dense Port Concentrators (DPCs) and Modular Port Concentrators (MPCs).

You can also configure the 100-Gigabit Ethernet MIC (MIC3-3D-1X100GE-CFP) to interoperate with routers using the 100-Gigabit Ethernet PIC (Type 4 1X100GE PIC for STFPC4 FPC) by using the forwarding-mode statement with the sa-multicast option at the [edit chassis fpc slot pic slot] hierarchy level. For more information, see Configuring 100-Gigabit Ethernet MIC (MIC3-3D-1X100GE-CFP) to Interoperate with 100-Gigabit Ethernet PICs (Type 4 1X100GE PIC for STFPC4 FPC) Using SA Multicast Mode.

The MPC3E is based on a new Junos OS chipset for increased scalability for bandwidth, subscribers, and service capabilities of the routers.

• Supports 100-Gigabit Ethernet interfaces
• Supports two separate slots for MICs
• Supported MICs: MIC3-3D-1X100GE-CFP, MIC3-3D-1X100GE-CXP, MIC3-3D-2X40GE-QSFPP, MIC-3D-20GE-SFP, and MIC-3D-2XGE-XFP
• Supports up to 100 Gbps per MIC slot
• Supports up to 200 Gbps aggregate WAN bandwidth connectivity for the two MIC slots; the line card is oversubscribed in the ratio of 1.5:1.
• Supports up to four full-duplex tunnel interfaces on the line card
• Supports intelligent oversubscription services

For more information about supported Junos OS features on the MPC3E, see Protocols and Applications Supported by the MX240, MX480, MX960 MPC3E in the MX Series 3D Universal Edge Routers Line Card Guide .

• Basic Layer 2 features and virtual private LAN service (VPLS) functionality
• Layer 3 routing protocols
• MPLS
• Multicast forwarding
• Firewall filters and policers
• Class-of-service (CoS) support
• Tunnel support
• Interoperability with existing DPCs and MPCs

At a high level, the MPC3E does not currently support these features:

• Fine-grained queuing and input queuing
• Unified in-service software upgrade (ISSU)
• Multilink services
• Internet Group Management Protocol (IGMP) snooping with bridging, integrated routing and bridging (IRB), or VPLS
• Intelligent hierarchical policers
• Precision time protocol (IEEE 1588)
• Synchronous Ethernet
• Virtual chassis support
