Juniper MX Series

MX-VC Configuration

The configuration of virtual chassis on the MX is very similar to the EX. The most challenging part is collecting the required information before creating the configuration. Each chassis that is to be part the virtual chassis must be identified, and a handful of information must be collected.

Warning

Be sure to use the console port on the routing engines as you configure virtual chassis; this will ensure that if a mistake is made, the connection to the router will not be lost.

Figure 6-19. Illustration of MX-VC Configuration Topology.

This section will build a MX-VC, as illustrated in Figure 6-19, using R1 and R2. The S1 switch will be used to create an IEEE 802.3ad interface into the MX-VC.

Chassis Serial Number

Virtual chassis uses the serial number to uniquely identify each chassis in the topology. It’s important to note that only the chassis serial number should be used. It’s easy to confuse other serial numbers such as a power supply or line card. Use the show chassis hardware command to find the chassis serial number. Let’s find the serial number for the R1 chassis:
