Hello group,
Any takers to this ?
I understand that with PIM-BIDIR no (S,G) entries are created. But when the
RP becomes unavailable, i assume that PIM will fallback from SM to DM. Maybe
not, if all the interfaces are configured as PIM-SM only. So i see the the
combinations that follow in order to avoid any (S,G) entries:
- PIM-BIDIR + all PIM interfaces configured in SM only.
- PIM-SM + interfaces configured in SM-DM + no ip pim dm-fallback
The command "ip pim spt-threshold infinity" does not resolve the problem in
the path from the RP upstream to the Source. At least one router will have
an (S,G) entry.
Thanks,
Antonio

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
