I'm looking to purchase a router that supports PIM DM multicasting. The 3Com NBX IP telephony system uses mutlicasting for certain features, and the routers must support PIM DM multicasting.
Does DD-WRT support this? Are there inexpensive routers out there that I can deploy? I imagine the old 3Com 5012 or 3026 will do the job, but I'm looking for something more "consumer grade" (like netopia or dd-wrt).
