Defines a maximum number of subnetworks this border node will search when looking for a resource. If no value is coded for SNVC, the value specified on the SNVC start option is used.

Note:

If SNVC=1 is coded, the search scope is restricted to the originating subnetwork. A value of SNVC=2 is required to allow a request to traverse one subnetwork boundary.
The maximum subnetwork count can be modified downwards if a node along the path has a lower SNVC count. However, the received SNVC is never modified upwards.
