Distributed Virtual Routing (DvR)

Note

Note

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

Maximum number supported

Note:
  • On the DvR leaf, you must enable the VRF scaling boot configuration flag if more than 24 VRFs are required in the DvR domain.

  • Scaling of the VSP 4450 Series controls the scaling of the DvR domain it is in. For example, if a VSP 4450 Series switch is in a DvR domain with other platforms such as VSP 7200 Series and VSP 8000 Series, the scaling of the entire domain is limited to the scaling of the VSP 4450 Series.

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.
