To create a chassis cluster with J-series services routers, you must physically connect a pair of the same kind of supported Juniper Networks services routers back-to-back over a pair of Gigabit Ethernet connections. The connection that serves as the control link must be the built-in interface ge-0/0/3. The fabric link connection can be a combination of any pair of Gigabit Ethernet interfaces on the routers. Figure 66 shows two services routers connected using the built-in interfaces for both the fabric and control links.
