That's a bittorrent local service discovery packet.
There is probably a BT torrent client running on the same machine (PY2EN)
with the AXIP tunnel endpoint.
Multicast packets get not routed without proper multicast support by PIM or
proxy, so it is probably a directly connected machine, no router in the
way, and it also uses the ax0 interface resulting in the shown behaviour.
