I have earlier reported that we had problem with Lantastic networks when they were connected to the backbone. Their ISO-like protocol caused interference to other ISO protocols ("HP-IP" in our case, most probably also AppleTalk Phase 2, Decnet Phase 5 and ISO-IP). This because they had no ISO headers following the length field. For quite a while we have now been running a new Lantastic version, the "Xerox" version. It is an Ethernet-2 protocol, they have changed the length field to have Ethernet type 81d6 instead. They are also using the following multicast addresses (in our case, they may differ in your case): ffff00600004 ffff00400001 ffff01e00004 The multicast traffic is about the same as for an Ethernet based VAX-cluster. Thanks to the Ethernet type we have had no problems what so ever with this Xerox version of Lantastic. If you want to filter it in a bridge, it can now also easily be done with just a type filter. The Lantastic users report the Xerox Lantastic to be stable. And all the previous features are retained, like very small memory consumption and easy installation and maintenance. If Lantastic is what you want, ensure you get the Xerox version and you don't any longer have to fear any interference with other traffic.
