If the value of vRtrIfProxyNDLocal is set to 'true', local proxy
Neighbor Discovery is enabled, that is, the interface will reply to
Neighbor Solicitation requests when both the hosts are on the same
subnet. In this case ICMP redirects will be disabled. If the value
of vRtrIfProxyNDLocal is set to 'false', the interface will not
reply to Neighbor Solicitation requests if both the hosts are on the
same subnet.
