Yes, it was intentionally dropped by the daemons. If it will be reachable, I will update the code accordingly.
I see it in the code now, just a couple of lines that can be deleted around line 1346:
/* drop 44.0.0.1 */ if (rip->address == inet_addr("44.0.0.1")) { #ifdef HAVE_DEBUG if (debug && verbose) fprintf(stderr, " - rejected\n"); #endif return; }
A temporary workaround until everyone has again updated ampr-ripd could be to announce 44.0.0.0/30 instead of 44.0.0.1/32 in the RIP sender.
