300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show ip policy Interface Route-map
FastEthernet0/0 PBR_MAP
R1# show route-map PBR_MAP
route-map PBR_MAP, permit, sequence 10 Match clauses:
ip address prefix-list MATCH_HTTP
Set clauses:
ip next-hop 10.10.10.2
Policy routing matches: 0 packets, 0 bytes
Based on this output, what is the most likely problem?
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 prefix-list MATCH_HTTP may not be matching any traffic, causing no policy routing.
The route-map PBR_MAP is applied to FastEthernet0/0 for policy routing, but the match counter shows 0 packets matched. This indicates that either the prefix-list MATCH_HTTP is not matching any traffic, or no traffic is hitting the interface. The correct answer is that the prefix-list may be misconfigured or not matching desired traffic.
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 route-map is not being applied to any interface.
Why it's wrong here
show ip policy shows it is applied to FastEthernet0/0.
- ✓
The prefix-list MATCH_HTTP may not be matching any traffic, causing no policy routing.
Why this is correct
0 packets matched indicates no traffic matches the prefix-list.
- ✗
The next-hop 10.10.10.2 is unreachable.
Why it's wrong here
The output does not indicate reachability; the match counter is 0.
- ✗
The route-map is configured with the wrong sequence number.
Why it's wrong here
