Data Center Fabric Reference Design Scaling Summary for Junos OS Release 19.1R2

 

This section shows the scale numbers for QFX10002-60C and QFX5120-32C switches. We support these switches in the Data Center Fabric validated topology starting in Junos OS Release 19.1R2.

Scaling for Centrally-Routed Bridging Overlays

Table 1 provides a summary of the scale numbers for QFX10002-60C switches acting as spine or border spine devices. Table 2 outlines the scale numbers for QFX5120-32C switches acting as spine devices. We added these switches, which were running Junos OS Release 19.1R2, to the existing Data Center Fabric validated centrally-routed bridging overlay.

These numbers do not represent the maximum supported scale. They represent only the initial solution testing performed.

Scaling for Edge-Routed Bridging Overlays

Table 3 provides the scale numbers for QFX10002-60C switches acting as border leafs and QFX5120-32C switches acting as server leafs. We added these switches running Junos OS Release 19.1R2 to the Data Center Fabric validated edge-routed bridging overlay.

These numbers do not represent the maximum supported scale. They represent only the initial solution testing performed.
