Campus Fabric IP Clos Deployment Types

Juniper’s Wired Assurance supports 3-stage and 5-stage IP Clos deployments. The 3-stage IP Clos is targeted for deployments that do not require a distribution layer and have smaller-scale requirements. This allows for cost-effective EX4400, EX4650, QFX5110, and QFX5120 switching platforms to be deployed at the core layer.
