Yes, that's very much a mystery, because my tcpdump shows the route being sent right after the one for 44.2.2.0/24.
[...] AFI IPv4, 44.2.2.0/24, tag 0x0004, metric: 1, next-hop: 24.52.189.1 AFI IPv4, 44.0.0.1/32, tag 0x0004, metric: 1, next-hop: 169.228.66.251
Could there be some length or count field that is off by one? I am tracing with wireshark (tshark). But ampr-ripd does not pick it up either.
