AutoRP disable in PIM-SM & PIM-SDM

[Catalin Sandu]

Hi,

Q1: Can we disable AutoRP ? If yes, how?

R1#sh ip pim autorp
AutoRP Information:
  AutoRP is enabled.

Q2: Does PIM-SM have dense mode fallback capability ? From what i've tested .. after clear ip mroute on all routers and clear ip pim rp map looks like PIM-SM doesn't have Dense Mode fallback capability .. and DM fallback works only for PIM-SDM ? Is it true ?

Thanks,

Hi Sandu,

By default fallback is enabled when you configure an interface with ip pim dense-mode or ip pim sparse-dense-mode.

Auto RP is not enabled by default unless you configure ip pim send-rp announce and ip pim send-rp-discovery

Hi,

Q1: you can't disable Auto-RP until 15.0(1)M where you can use the no ip pim auto-rp command.

Q2: correct
