IP SLA and EIGRP: Why Tracking Doesn't Work

This 300-410 practice question tests your understanding of ip sla. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

An engineer configured IP SLA 20 to monitor the reachability of a next-hop router (192.168.1.1) using UDP jitter probes. The goal is to use the IP SLA with a track object to influence EIGRP route selection. However, the EIGRP route is not being affected by the IP SLA state. The engineer verifies that the IP SLA is 'Active' and the track object shows 'Up'. What is the most likely misconfiguration?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
The IP SLA probe type (UDP jitter) is not supported for tracking EIGRP routes.
Why wrong: UDP jitter is supported for IP SLA; the probe type is not the issue.
B
The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.
EIGRP does not have a mechanism to directly track IP SLA states. The engineer must use a tracked static route or policy-based routing to influence traffic.
C
The EIGRP route has a higher administrative distance than the tracked route.
Why wrong: Administrative distance is not related to IP SLA tracking; the route is still present but not affected by the track state.
D
The IP SLA threshold is set too low, causing flapping.
Why wrong: The track object shows 'Up', so the threshold is not causing flapping.

Quick Answer

The answer is that EIGRP does not support direct tracking of IP SLA for route metrics, so the track object must be applied to a static route or redistribution policy rather than to EIGRP itself. The core technical concept is that IP SLA tracking operates at the interface or static route level, not within EIGRP’s dynamic routing process; EIGRP selects routes based on its composite metric and neighbor reachability, not on the state of a track object. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding of how IP SLA and EIGRP interact—a common trap is assuming that a track object tied to an IP SLA will automatically influence EIGRP’s routing table, but in reality, you must use a tracked static route as a floating default or manipulate redistribution to affect EIGRP’s decision. The search intent “IP SLA not affecting EIGRP” often arises when engineers forget that EIGRP ignores track objects natively. Memory tip: “EIGRP tracks neighbors, not SLA probes—static or redistribute to make it notice.”

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

✓

The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.

EIGRP does not natively react to IP SLA track objects unless the route is redistributed or a static route with tracking is used. The engineer likely expected EIGRP to automatically adjust metric based on IP SLA, which is not supported.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

✗
The IP SLA probe type (UDP jitter) is not supported for tracking EIGRP routes.
Why it's wrong here
UDP jitter is supported for IP SLA; the probe type is not the issue.
✓
The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.
Why this is correct
EIGRP does not have a mechanism to directly track IP SLA states. The engineer must use a tracked static route or policy-based routing to influence traffic.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The EIGRP route has a higher administrative distance than the tracked route.
Why it's wrong here
Administrative distance is not related to IP SLA tracking; the route is still present but not affected by the track state.
✗
The IP SLA threshold is set too low, causing flapping.
Why it's wrong here
The track object shows 'Up', so the threshold is not causing flapping.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Quick reference

Routing Protocol Comparison

Protocol	Metric	Max Hops	Algorithm	Type
RIP v2	Hop count	15	Bellman-Ford	Distance vector
OSPF	Cost (bandwidth)	Unlimited	Dijkstra (SPF)	Link state
EIGRP	Composite metric	Unlimited	DUAL	Hybrid
IS-IS	Cost	Unlimited	Dijkstra	Link state
BGP	Policy / attributes	Unlimited	Path vector	Path vector

RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
