300-410 Practice Question: Runs the following command to troubleshoot BFD…

A network engineer runs the following command to troubleshoot BFD with static routes:

R1# show ip route 10.8.8.0/24

Routing entry for 10.8.8.0/24 Known via "static", distance 1, metric 0 Routing Descriptor Blocks:

* 10.9.9.2, via GigabitEthernet0/3

Route metric is 0, traffic share count is 1 BFD enabled, BFD state: UP

What does this output indicate?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Static route is installed with BFD tracking, and BFD session is UP.

The output shows that BFD is enabled for the static route and the BFD state is UP, meaning the next hop is reachable and BFD is providing fast failure detection.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Static route is installed with BFD tracking, and BFD session is UP.

    Why this is correct

    The route is installed from a static source with BFD tracking attached, and the session state shows UP, confirming the neighbour is reachable and the route is actively forwarding. BFD failure would withdraw the route.

  • ✗

    Static route is not using BFD.

    Why it's wrong here

    The output explicitly shows "BFD enabled, BFD state: UP" against the static route's next hop, so BFD is actively tracking it. It is tempting because a route can exist without BFD, and that would be the correct reading had the descriptor block omitted any BFD line.

  • ✗

    BFD state is DOWN, so the static route is removed.

    Why it's wrong here

    The output states "BFD state: UP", so the session is healthy and the route remains installed; a DOWN state would trigger removal. It is tempting because BFD does withdraw static routes when sessions fail, which would be the correct reading had the state shown DOWN.

  • ✗

    Static route is using BFD only for IPv6.

    Why it's wrong here

    The descriptor block shows BFD enabled with state UP on an IPv4 static route (10.8.8.0/24), so BFD is not IPv6-only here. It is tempting because BFD does support IPv6 peers, and that would apply to a route whose prefix and next hop were IPv6 addresses.
