Collapsed Core EVPN-VXLAN with EVPN Multihoming Campus Network Scaling Data

 

Table 1 lists the scaling values for the EX4650 switch and Table 2 lists the scaling values for the QFX5120 switch operating as distribution nodes in the EVPN-VXLAN collapsed core with EVPN multihoming example. You can find the topology and configuration in How to Configure a Campus Network using EVPN Multihoming. These numbers do not represent the maximum supported scale. They represent only the solution testing performed for this example. The results of the tests are provided for reference purposes only.
