RE: Multicast Autorp RP-election process

Hi Julio,

This is the usage guideline from the DocCD Command Ref:

"Usage Guidelines

Use the ip pim autorp listener command with interfaces configured for PIM
sparse mode operation in order to establish a network configuration where
Auto-RP operates in PIM dense mode and multicast traffic can operate in
sparse mode, bidirectional mode, or Source Specific Multicast (SSM) mode."

As far as I know, this command has no impact on the Auto RP election
process, which is just based on highest IP amongst RPs claiming a given
group or range.

Regards,

Scott

Hello Group,

I have a silly trouble.
If you have all your router configured with Sparse-mode, and autorp
listener,
and there are two routers claiming to be the RP for the same group (with ip
pim send-rp-announce), What router will become the RP for the group ??

Thanks,
Julio
