vRtrRipInstanceEntry is an entry (conceptual row) in the
vRtrRipInstanceTable. Each entry represents the configuration
for a RIP instance.
Entries in this table cannot be created and deleted via SNMP SET
operations. An entry in this table is created by the agent when
vRtrRipStatus in the vRtrConfTable is set to 'create(1)'. The entry
is destroyed when vRtrRipStatus is set to 'delete(2)'.
