- Well, most routers in the world do. That is because cause nearly all
- routers in the world are UNIX workstations and PC's, instead of
- Official Real Routers (tm) and since mrouted & friends work in common
- workstations. Someone once observed that Sun all by itself has
- probably shipped more "IP routers" than all of the "router vendors"
- combined.
-
- It is often enough to just get mrouted running on the workstations you
- are using as routers.
-
- You'll notice that an official class-D address has been registered for
- the portmapper, 224.0.2.2.
-
-
- In the sense you probably meant the question, I don't know. For years
- I hounded router vendors at Interop, and was always told "wait for
- OSPF." Then they started saying "wait until the replacement for the
- distance-vector-multicast-routing-protocol." This year I didn't
- bother.
-
- The IETF Entertainment Network should finally give the router vendors
- enough reason to finish the work.

- P.S. I hope no one finds it necessary to point out all of the reasons
- to use an Official Real Router (tm) instead of a workstation, or the
- other way around. I trust anyone who cares is already quite familiar
- with all sides of that old argument.
