DvR Deployment for Wireless Roaming in Campus Deployments

In fabric deployments where IP subnets/I-SIDs stretch between multiple buildings, you can use DvR instead of VRRP or RSMLT to avoid traffic tromboning issues. This deployment is supported with non-fabric switches that have Fabric Attach enabled, or switches that do not support Fabric Attach. You can use VSP 4450 Series as DvR Leafs in this context as well. IP subnets can stretch across one or multiple DvR domains as shown in the following figure.
