The Juniper Networks MX5, MX10, MX40, and MX80 3D Universal Edge Routers are
Ethernet-optimized edge routers that provide both switching and carrier-class Ethernet
routing. The MX5, MX10, MX40, and MX80 routers run Junos operating system (Junos
OS), enabling a wide range of business and residential applications and services, including
high-speed transport and virtual private network (VPN) services, next-generation
broadband multiplay services, and high-volume Internet data center internetworking.
Each router provides full duplex, high-density Ethernet interfaces and high- capacity
switching throughput and uses the Junos Trio chipset for increased scalability of L2/L3
packet forwarding, buffering, and queuing.
The routers each contain a built-in Routing Engine and one Packet Forwarding Engine.
The Packet Forwarding Engine has two "pseudo" Flexible PIC Concentrators (FPC 0 and
FPC1). Because there is no switching fabric, the single Packet Forwarding Engine takes
care of both ingress and egress packet forwarding.
The routers are compact and two rack units (U) tall. Several routers can be stacked in a
single floor-to-ceiling rack for increased port density per unit of floor space.
For scalable configuration options you can install a variety of Modular Interface Cards
(MICs) in the two front slots of the router, and the optional Multiservices MIC can be
installed in the rear slot. Software licenses allow you to upgrade from one router to
another without a hardware upgrade. The ports are restricted based on the router's
associated license as follows:
