- A
All routes are redistributed with metric 50.
Why wrong: Only routes matching ACL 10 get metric 50; others are denied.
- B
Routes matching ACL 10 are redistributed with metric 50; routes matching ACL 20 are denied; all other routes are also denied.
This matches the route-map logic.
- C
Routes matching ACL 20 are redistributed with default metric.
Why wrong: Sequence 20 is deny, so those routes are not redistributed.
- D
The route-map has no effect because set clauses are missing in sequence 20.
Why wrong: The deny action still prevents redistribution.
Question 1,239 of 2,152
Route-Map Redistribution Logic
This 300-410 practice question tests your understanding of device management. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
A network engineer runs the following command on Router R1:
R1# show route-map TEST
route-map TEST, permit, sequence 10 Match clauses:
ip address (access-lists): 10
Set clauses: metric 50 route-map TEST, deny, sequence 20 Match clauses:
ip address (access-lists): 20
Set clauses:
Based on this output, what is the effect of this route-map when applied to a redistribution command?
Quick Answer
The correct answer is that routes matching ACL 10 are redistributed with metric 50, routes matching ACL 20 are denied, and all other routes are also denied. This is because a route-map applied to redistribution uses an implicit deny at the end, meaning any route that does not match a permit sequence is automatically blocked. Sequence 10 explicitly permits and sets the metric, while sequence 20 explicitly denies, so only ACL 10 traffic passes through. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding of route-map redistribution logic and the critical default behavior: without a final permit statement, everything not matched is dropped. A common trap is assuming unmatched routes are permitted by default—they are not. Remember the mnemonic: “Permit to pass, deny to drop, implicit deny stops the shop.”

Correct answer & explanation
✓
Routes matching ACL 10 are redistributed with metric 50; routes matching ACL 20 are denied; all other routes are also denied.
Option B is correct because route-map TEST processes sequences in order. Sequence 10 permits routes matching ACL 10 and sets their metric to 50. Sequence 20 denies routes matching ACL 20. Since there is no explicit permit for other routes, the implicit deny at the end of the route-map denies all unmatched routes. Thus, only routes matching ACL 10 are redistributed with metric 50.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
The deny action still prevents redistribution.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the implicit deny at the end of a route-map, leading candidates to forget that unmatched routes are denied, not permitted with default values.
Detailed technical explanation
How to think about this question
Route-maps are evaluated in sequence order, and each sequence can have match and set clauses. The implicit deny at the end of a route-map is a fundamental behavior: any route that does not match a permit sequence is denied. In redistribution, a route-map controls which routes are injected into the routing protocol and optionally modifies attributes (e.g., metric). The set clause in a deny sequence is irrelevant because the route is not redistributed. This behavior is consistent across all routing protocols (OSPF, EIGRP, BGP) when using route-maps for redistribution.
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.
TExam Day Tips
- 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 security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.

The correct answer is: Routes matching ACL 10 are redistributed with metric 50; routes matching ACL 20 are denied; all other routes are also denied. — Option B is correct because route-map TEST processes sequences in order. Sequence 10 permits routes matching ACL 10 and sets their metric to 50. Sequence 20 denies routes matching ACL 20. Since there is no explicit permit for other routes, the implicit deny at the end of the route-map denies all unmatched routes. Thus, only routes matching ACL 10 are redistributed with metric 50.
