It was very, very basic! And kind of an disappointment... plus the setup portions weren't "complete" in the sense that sometimes they wouldn't tell you, you need to configure a loopback as an interface or provide verification commands and the output.
2 things that I did learn, MSDP and Stub Multicast routing.
MSDP - Multicast Source Discovery Protocol - Peer 2 RPs from different multicast domains in order to propagate mutlicast traffic to clients on/through a different domain. The peering take place between 2 RPs, so RP configs need to be applied.
ip msdp peer A.B.C.D connect-source S1/0.2
Stub Routing - you can filter PIM neighbor relations through ip pim neighbor-filter 1. The acl specifies the hosts of the other PIM routers. On the stub router, under the interface that faces the multicast host clients, configure ip igmp helper-address a.b.c.d . It's basically the same as an ip helper address for DHCP.
Things that weren't covered, IP PIM NBMA mode, Auto-rp Listner for Sparse Modes, group-lists, rp-lists. etc.
... up next, Access-lists.
