Description
When you configure multicast-only fast reroute (MoFRR) in a PIM domain, allow only a disjoint RPF (an RPF on a separate plane) to be selected as the backup RPF path.
In a multipoint LDP MoFRR domain, the same label is shared between
parallel links to the same upstream neighbor. This is not the case
in a PIM domain, where each link forms a neighbor. The mofrr-disjoint-upstream-only statement does not allow a backup RPF path to be selected if the
path goes to the same upstream neighbor as that of the primary RPF
path. This ensures that MoFRR is triggered only on a topology that
has multiple RPF upstream neighbors.
