Custom Virtual Interface Priorities

CVI priorities are set according to the degree of specificity of the subnet mask that you provide. Subnet masks that are most specific are highest priority. If you configure a CVI for an IP address with a subnet mask that denotes a single node (such as 192.168.20.2/32), the CVI has the highest priority. If you specify an IP address with a subnet mask that identifies multiple possible nodes (such as 192.0.0.0/8), the CVI has a lower priority. Establishing priorities in this way helps ensure that CVI traffic to a host on a large subnet remains separate from other traffic on the subnet.

Note: Reports that are generated for traffic between two CVIs with the same priority can be inconsistent.
