Note
Local hosts use ARP entries and remote hosts use host entries. For information on IP ARP scaling, see IP Unicast.

| DvR Virtual IP interfaces | VSP 4900 Series | 499 with vIST 500 without vIST | 
| VSP 7400 Series | 999 with vIST as interior node 1,000 without vIST as interior node 500 on boundary node | |
| DvR domains per SPB fabric | VSP 4900 Series | 16 | 
| VSP 7400 Series | 16 | |
| Controller nodes per DvR domain with default route inject flag enabled Total number of Controllers per domain cannot exceed 8. Note: 
                                     A DvR domain containing only Controller nodes and no Leaf nodes can have more than 8 Controllers per domain. | VSP 4900 Series | 8 |

| Leaf nodes per DvR domain | VSP 4900 Series | 250 | 
| VSP 7400 Series | 250 | |

| DvR host route scaling per DvR domain (scaling number includes local as well as foreign hosts of the Layer 2 VSN that are members of the domain) If DvR Layer 2 VSNs span DvR domains, and all DvR Controllers have an IP interface on the Layer 2 VSNs, then the DvR host scaling is network-wide, as DvR Controllers will consume as many host routes as there are hosts across all DvR domains. | VSP 4900 Series | 32,000 | 
| VSP 7400 Series | 40,000 | |
