Nov 19, 2021:

VMware presented the design approaches.
Discussed the 2 design approaches for MLD and PIMv6 development.
Design 1: Have one daemon, include pimv6 and pimv4 code in the single daemon. Both will run together.
Design 2: Have 2 separate daemons, 1 running pimv4 and another running pimv6. But both sharing the common code.
We agreed upon Design 2. (Members from VMware and Dell, Donald participated in this meeting)
Refer the PPT for details. https://github.com/FRRouting/frr/files/7658464/IPv6.Multicast.Design.-.Community.pptx

Dec 2, 2021:

Considered one more design approach where we can run pimv6 as a thread inside the same daemon.
After considering all the 3 design approaches, we concluded on using Design 2.
We shared the Yang model design as well.
