Netlab should have a multicast module.

[DanPartelly]

Multicast is another major item we miss in Netlab. It's time to implement it, if everybody agrees we should have it. I will do the implementation.

If there an agreement, Ill start a discussion on the data model , and the feature set we agree to support.

if everybody agrees we should have it.

Absolutely

I will do the implementation.

Thank you! I would start with some minimal subset of features, like maybe PIM-SM and IGMP joins?

@DanPartelly thank you for looking into this!

Currently, I'm running a playbook post netlab up to configure multicast on a part of my lab, with IOS and one Arista devices. I had a surprise with a recent version of Arista cEOS (IIRC it started with 4.35) where you can't run globally ip pim ssm range 232.0.0.0/8 you now have to enable it per interface pim ipv4 sparse-mode

If somewhat useful, I've attached the playbook:
