MANET Routing Alternatives MANET routing as a L2 mechanism w/no L2 multicast flooding – MANET looks like an NBMA link that connects routers/gateways (no gateway discovery; not considered further) MANET routing as a L2 mechanism w/L2 multicast flooding - MANET looks like a bridged campus LAN (no special MANET Autoconf extensions needed) MANET routing as a L3 mechanism w/no L3 multicast flooding – MANET looks like multiple links w/no multicast (no gateway discovery; not considered further) MANET routing as a L3 mechanism w/L3 multicast flooding – MANET looks like multiple links w/MANET-wide (site-scoped) multicast (subject of this proposal) |
