I think that they took the old CP/M version of Karn's code and ported it
to an 8051.

But what good is it if it doesn't speak TCP/IP? Bill Wisner wisner@mica.berkeley.edu ucbvax!mica!wisner I'm not poricthys notatus either.

I understand that some appliances do not yet implement split horizon, in particular some refrigerators. Perhaps if they tried a link state algorithm...

Of course, this is an illegal activity, as net 224 is reserved for Multicast addresses. In particular 224.0.0.5 and 224.0.0.6 are assigned to the OSPF IGP routing protocol. I believe also that it is illegal to forward a packet from or to net 224 as this is part of the range of addresses are that are explicitly single-hop! Thanks, Milo
