This variable should only be associated with secondary
ip addresses, i.e., when the value of vRiaIndex is other
than 1. When vRiaIgpInhibit has a value of 'true',
it indicates that the given secondary IP address should
not be recognized as a local interface by the running IGP.
For OSPF and IS-IS, this means that the given secondary
IP addresses will not be injected as passive interfaces
and will not be advertised as internal IP interfaces into
the IGP's link state database. For RIP this means these
secondary IP interfaces will not source RIP updates.
