All,
Just started on this I have many issues to resolve using autorp as it would
like sparse-dense ideally.
I have tried "ip pim autorp listener" but some of my kit is on IOS that
doesn't support it.
I quickly tried bootstrap and all is well.
I have tried this across nbma, point2m and broadcast over the hub and spoke
frame-relay.
Not a detailed technical input but it might help you on your way.
