Multicast

RFC 8815 deprecated PIM-SM so PIM-SSM is the way to go!

Setup

For it to work, you’ll need to do the following:

• Ask your peering to enable ipv4/ipv6 multicast AFI on your peering
• Set up IPv4/IPv6 PIM for the (s,g) joins to pass through
• Be prepared to setup IGMP v3 and MLD v2 from your listeners

You’re done! You should receive the multicast routes from peers advertising them.

FRR configuration used by C4TG1RL5. Please make sure you understand how to configure and use frr before you use anything from this configuration!
