Details:

The following socket options related to multicast for IPv6 seem to be
missing:

IPV6_MULTICAST_LOOP
IPV6_MULTICAST_HOPS
IPV6_MULTICAST_IF

(see http://man7.org/linux/man-pages/man7/ipv6.7.html)

These options are used by the open62541 library for implementing OPC UA PubSub
(see https://open62541.org/).
