Subject: PIM neighbors on a LAN: SPARSE or DENSE

Hi!

I wonder how a CISCO learns which of its PIM neighbors on a LAN
interface is SPARSE and which is DENSE. 

"show ip pim neighbor" gives such info.

Does CISCO use some undocumented option in PIM HELLO messages to inform
other neighbors of the configured mode of the LAN interface?

Thank you.

Best regards,
