[snip description of XMR load-balancing working]
I'm not sure I see anything wrong with your description. Generally,
load-balancing algorithms use src and dst IP addresses and TCP/UDP port
numbers or ICMP sequence. Not all equipment balances IPv6 and multicast
traffic as nicely as most do IPv4.
Given a recent amount of entropy, hash-based load-balancing works quite
well, in my experience. The XMR can do per-packet too. Just be aware
that that might in some cases lead to packet reordering. And stay away
from "switch trunks" (support for which the XMR deprecates).
