A regional planning commission evaluates EIGRP IP FRR (single-hop) to pre-arm a backup next hop for a civic core link. What is the core idea of this fast-reroute approach?
Select an answer to reveal the explanation.
Short Explanation
IP FRR is packing a spare chute before you jump—the backup next hop is already chosen. When the primary link snaps, forwarding pivots locally instead of waiting for the whole DUAL meeting. Faster protection, same EIGRP neighborhood.
Full Explanation
EIGRP IP FRR / LFA-style protection pre-installs a loop-free alternate next hop so data-plane failover can occur immediately on local failure detection, before complete control-plane reconvergence. It does not replace EIGRP with MPLS TE by definition, nor does it intentionally slow SPF/DUAL or inflate hellos. Single-hop scope targets directly connected backup nexthops in the civic core.
