Which two options are characteristics of MoFRR? ( Choose two)
A. Uses additional PIM join toward source
B. Based on multicast forward error correction feature
C. Based on PIM Fast Route
D. Requires MPLS TE FRR enabled with link protection and node protection
E. Utilizes two equal-cost paths toward source
A & E
only A
MoFRR transmits a multicast join message from a receiver toward a source on a primary path, while also transmitting a secondary multicast join message from the receiver toward the source on a backup path. Data packets are received from both the primary path and the secondary paths. The redundant packets are discarded at topology merge points due to Reverse Path Forwarding (RPF) checks. When a failure is detected on the primary path, the repair is made by changing the interface on which packets are accepted to the secondary interface.Because the repair is local, it is fast–greatly improving convergence times in the event of node or link failures on the primary path.
