Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain?

The most appropriate technique to detect forwarding path failures at a uniform rate and ensure consistent and predictable reconvergence times in the same broadcast domain is to enable Bidirectional Forwarding Detection (BFD) on the routers.
BFD is a lightweight protocol that runs directly on the data plane and is used to detect path failures quickly. It operates at a much faster rate than other routing protocols, allowing for faster detection and recovery times. BFD continuously monitors the forwarding path between two routers and notifies them of any path failures.
Configuring IP-SLA to ping the peer router, as suggested in option B, is a valid technique for detecting path failures, but it may not be as fast and reliable as BFD. Additionally, it does not ensure consistent and predictable reconvergence times.
Option C suggests configuring IP-SLA and track to ping the peer and switch to a default route if the pings fail. This technique can be useful for providing a backup path in case of a failure, but it does not address the question's requirement of consistent and predictable reconvergence times.
Tuning routing protocol timers, as suggested in option D, may help improve the routing protocol's convergence time. However, it does not ensure a uniform rate of failure detection or predictable reconvergence times.
In summary, the most appropriate technique to detect forwarding path failures at a uniform rate and ensure consistent and predictable reconvergence times in the same broadcast domain is to enable BFD on the routers.
