Hi Antonio,

Reading that requirement, my choice would be to use spt-threshold
infinity.

Using this, routers downstream of the RP will just be using the (*,G)
route and won't try to switch to an (S,G). I'm not sure that the other
two options you presented will do that.

Subject: Avoiding (S,G) Entries

Hello group,

I have some problems with the task wording when it calls to avoid (S,G)
entries in the Mcast Routing Table.

I see 3 options and i would like to have your inputs regarding the
different behaviours we get with each command:

- ip pim bidir-enable and ip pim rp-address x.x.x.x bidir

- no ip pim dm-fallback

- ip pim spt-threshold infinity

Thanks,
Antonio
