And even in O/S's there's a patch to FreeBSD 4.8 which adds multipath support at http://www.dsm.fordham.edu/~tanzer/multipath/ i've tested it on FreeBSD 4.9 and it works, with the addition of an additional modification. see another thread in -net for details. > sigh... someday BSD's will decide to better support M-Homing.. for now > hacks are appropriate :-/ yes they are. i'm exploring to see if i can implement multipath functionality as a new netgraph node. this, for starters, would at least to an extent provide modularity to the existing mpath patches referenced above and back porting to earlier 4.x systems without modifying the core tcp/ip stack of freebsd. one possible addition to functionality in this yet-to-be-written node could perhaps be a heartbeat to the next hop router and to down that route/interface if the next hop was down for any reason.
