This creates a DCL command file that may be used to aid setting up networks
 that use both DECnet-Plus and DECnet Phase IV level 2 routing protocols (link
 state and routing vector protocols).

 The command file is used to create or delete interphase link entries in
 a DECnet-Plus level 2 router's reachable address table.  This is used on a
 DECnet-Plus level 2 router that must route messages between a DECnet-Plus
 level 2 network and a DECnet Phase IV level 2 network.
