The value of vRtrPimNgIfImprovedAssert specifies whether to
enable or disable improved assert processing on this interface.
The PIM Assert process establishes a forwarder for a LAN and
requires interaction between the control and forwarding planes.
The Assert process is started when data is received on an
outgoing interface. This could impact performance if data
is continuously received on an outgoing interface.
If this flag is set to 'true', the PIM assert process is done
entirely on the control-plane with no interaction between the
control and forwarding plane.
