Static M-cast and Auto-rp
Auto-RP uses the election of highest RP ip address as the tie-breaker. Since Auto-RP mapping agents use the highest RP for each group or range of multicast addresses, Auto-RP provides redundant RP capability.
If you have configured static RP with override feature, static RP has the highest precedence over Auto-RP. Static RP does not have a backup, if it fails, depending on the multicast mode set on the interface, a lost of RP may resulted in Dense-mode fallback.
For smaller address to become the RP, you need to use BSR (PIM v2) with the priority command feature which is not available to Auto-RP.
