A network engineer runs the following command on Router R1:
R1# show ip policy Interface Route-map
GigabitEthernet0/1 PBR-MAP
R1# show route-map PBR-MAP
route-map PBR-MAP, permit, sequence 10 Match clauses:
ip address (access-lists): 101
Set clauses:
ip next-hop verify-availability 10.1.1.2 10 track 1
Policy routing matches: 150 packets, 12000 bytes
R1# show track 1 Track 1 IP SLA 1 reachability
Reachability is Down 1 change, last change 00:05:20 Latest operation return code: timeout
Tracked by:
ROUTE-MAP 0
Based on this output, what is the most likely outcome?
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
✓
Packets matching ACL 101 are routed normally via the routing table.
The route map uses 'ip next-hop verify-availability' with tracking. Track 1 is down because IP SLA 1 reports unreachability. Therefore, the set clause will not be applied, and packets matching ACL 101 will not be forwarded to 10.1.1.2; they will be routed normally via the routing table.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Packets matching ACL 101 are forwarded to 10.1.1.2 regardless.
Why it's wrong here
The verify-availability feature checks the track object; since track 1 is down, the next-hop is not used.
- ✗
Packets matching ACL 101 are dropped.
Why it's wrong here
PBR does not drop packets when the set clause is not applied; they are forwarded using the routing table.
- ✓
Packets matching ACL 101 are routed normally via the routing table.
Why this is correct
When the tracked object is down, PBR skips the set clause and the packet is forwarded using the destination-based routing table.
- ✗
The route map is removed from the interface due to the track failure.
Why it's wrong here
The route map remains applied; only the next-hop selection is affected.

Key term
IP SLA for Path Control
IP SLA for Path Control is a Cisco technology that uses active network measurements to dynamically influence routing decisions and redirect traffic along a preferred path when network conditions change.
Key term
Policy Based Routing
Policy Based Routing (PBR) is a technology that allows network traffic to be forwarded based on user-defined policies rather than just the destination IP address in the routing table.

Variation 1. A network engineer runs the following command on Router R1: R1# show ip policy Interface Route-map GigabitEthernet0/0 PBR-TRACK R1# show route-map PBR-TRACK route-map PBR-TRACK, permit, sequence 10 Match clauses: ip address (access-lists): 170 Set clauses: ip next-hop verify-availability 10.0.0.2 10 track 2 Policy routing matches: 100 packets, 8000 bytes R1# show track 2 Track 2 IP SLA 2 reachability Reachability is Up 2 changes, last change 00:01:30 Latest operation return code: ok Tracked by: ROUTE-MAP 0 R1# show ip route 10.0.0.2 Routing entry for 10.0.0.2/32 Known via "eigrp 1", distance 90, metric 28160 Last update from 192.168.1.2 on GigabitEthernet0/1 Based on this output, what is the most likely behavior for packets matching ACL 170?
medium- ✓ A.Packets are forwarded to 10.0.0.2.
- B.Packets are forwarded using the routing table because the next-hop is not reachable.
- C.Packets are dropped because the track object is not configured correctly.
- D.Packets are load-balanced between the next-hop and the routing table.
Why A: The route map uses 'ip next-hop verify-availability' with track 2. Track 2 is Up (IP SLA 2 reachability is ok). Therefore, the next-hop 10.0.0.2 is considered available, and packets matching ACL 170 are forwarded to 10.0.0.2.
