The next available Virtual Router Id (index). This object provides a hint for the rcVrfId value to use when administratively creating a new rcVrfConfigEntry.

A GET of this object returns the next available rcVrfId value to be used to create an entry in the associated rcVrfConfigTable; or zero, if no valid rcVrfId value is available. A value of zero(0) indicates that it is not possible to create a new rcVrfConfigEntry. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that ifIndex allocation is unintended.

Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously.

Unless specified otherwise by its MAX-ACCESS and DESCRIPTION clauses, an object of this type is read-only, and a SET of such an object returns a notWritable error.
