MT says that it's an incompatible extension of an early draft of HWMP. I don't know where HWMP is now or why they forked it. But we're looking for an off-the-shelf short term solution, while we, uh, work on the long-term answer. The nice thing about Routerboards is that you can run other Linux code on them... >But please, do not get discouraged and in case HWMPplus does indeed >work with more >than 100 nodes, let me know and I would be very interested in how >you managed to do that. > >Of course, your mileage or your needs might differ. The site I have in mind would need fewer than 50 nodes. So how many hops and how many nodes would be reasonable limits for HWMPplus? -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701 -------------------------------------------------------------------------------- WISPA Wants You!
