The term "RE2" is a specific model of the Routing Engine, predominantly found in Juniper's legacy M-series routers (such as the M5, M10, M20, M40, and M160). It marked a significant step forward in processing power for its time. Key specifications of the RE2 include:

While standard LAG works between two devices, takes the concept a step further. It allows a client device to form a LAG with two separate Juniper devices (MC-LAG peers) simultaneously. SRX340 control link wont establish over layer 2

The Juniper Ren 2 link is a foundational technology behind Juniper’s ability to build massive, carrier-grade routers. While invisible to the end-user, its proper operation is essential for the non-stop forwarding, resiliency, and scaling that service providers and large data centers rely on. As Juniper moves toward higher-density systems (e.g., Ren 3, Ren 4), the Ren 2 remains widely deployed in mature networks as a reliable and battle-tested fabric interconnect.

For network engineers using Junos OS, the terms and "link" (logical interface link/properties) represent core commands used to manage physical interfaces, loopbacks, and bundle configurations.

Configuring redundancy for an RE-2 is done within the Junos OS CLI. Here’s a basic snippet of how you might set the master role:
