the topology is like this:
S - RP - MA - PIM R - Hosts
I've two questions about Auto-RP PIM mode:
1) from S (sources) to RP, and from RP to MA (mapping agent), I need to use 'sparse-dense' mode, or is enough 'sparse-mode' (without autorp listener)?
2) the best practice with Auto-RP is to use sparse mode with autorp listener, or sparse-dense mode with a "sink" RP for unknown mGroups?
Any advice will be appreciated
