BSR and dm-fallback

Hi group,

I have a question regarding the command "no ip pim dm-fallback".
My understanding is, that this one can be used on interfaces configured in
"ip pim sparse-dense-mode" to prevent the interface to fall back to
dense-mode operation if a RP cannot be found.

Further, the IP Multicast configuration Guide says: "A BSR performs
similarly as an RP, except that it does not run the risk of reverting to
dense mode operation, and it does not offer the ability to scope within a
domain." (page 55)

However, section "Configuring Sparse Mode with a Bootstrap Router" on page
80/81 also has the command "no ip pim dm-fallback" included. Do we really
need that command when running BSR over sparse-mode?

Thanks
Mike
