Review the following restrictions and behavioral characteristics associated with DvR.
The DvR feature does not affect out-of-band management on a switch chassis, if the chassis supports it.
The DvR feature does not support a non-DvR BEB in a DvR-enabled Layer 2 VSN.
Note
If the DvR Controller supports it, you can configure Virtual Router Redundancy Protocol (VRRP) on DvR I-SIDs to permit traffic routing from non-DvR Backbone Edge Bridges (BEBs) outside of the domain. For more information, see DvR-VRRP Coexistence. For information on DvR Controller support, see Fabric Engine Feature Support Matrix.
The number of host route records that can be stored in the data path of a Leaf node is limited to the scaling capacity of the switch node. Different switch platforms have different scaling capacities.
For information on the scaling capacities of different platforms, see Fabric Engine Release Notes.
You must first disable DvR on a Controller or Leaf node, before you attempt to change the domain ID of the node.
You cannot configure IGMP snooping on DvR-enabled nodes.
In any DvR ISID the only supported VRRP routers are DvR Controllers with DvR VRRP enabled. Interoperation with non-DvR VRRP routers is not supported.
