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 VSP 4450 Series scaling information, see VOSS Release Notes for VOSS Release 8.10.

A DvR domain containing only Controller nodes and no Leaf nodes can have more than 8 Controllers per domain.

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.
