This read-create TruthValue indicates whether the interface is treated as a point-to-point link where DVMRP neighbors are not required to send Hello messages, provided for compatibility with older DVMRP implementations that skip Hellos on point-to-point links. An admin enables it when peering with a legacy DVMRP router over a point-to-point circuit that doesn't send Hellos, so the local router doesn't incorrectly declare the neighbor down. For example, a serial WAN link to an older DVMRP-speaking router might need this set to true to keep the adjacency stable.
