<tag>ptp netmask <m/switch/</tag>
In <cf/type ptp/ network configurations, OSPFv2
implementations should ignore received netmask field in hello
packets and should send hello packets with zero netmask field
on unnumbered PtP links. But some OSPFv2 implementations
perform netmask checking even for PtP links. This option
specifies whether real netmask will be used in hello packets
on <cf/type ptp/ interfaces. You should ignore this option
unless you meet some compatibility problems related to this
issue. Default value is no for unnumbered PtP links, yes
otherwise.

If set, a hardware link state (reported by OS) is taken into
consideration. When a link disappears (e.g. an ethernet cable is
