Router R4 has the following configuration:
```
interface GigabitEthernet0/5 ip address 10.4.4.4 255.255.255.0 ip policy route-map PBR-DEFAULT
! route-map PBR-DEFAULT permit 10 set ip default next-hop 192.168.3.1 ``` What is the effect of this configuration?
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
✓
All packets received on G0/5 are forwarded to 192.168.3.1 if they do not have a route in the routing table.
The 'set ip default next-hop' command is used for packets that do not match any explicit route in the routing table. It does not affect packets that have a matching route.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All packets received on G0/5 are forwarded to 192.168.3.1 if they do not have a route in the routing table.
Why this is correct
Default next-hop applies only when the routing table has no route for the destination.
- ✗
All packets received on G0/5 are forwarded to 192.168.3.1 regardless of the routing table.
Why it's wrong here
That would be 'set ip next-hop', not 'set ip default next-hop'.
- ✗
The route-map is missing a match statement, so it does nothing.
Why it's wrong here
A route-map without a match statement matches all packets, so it is valid.
- ✗
The configuration is invalid because 'set ip default next-hop' requires an ACL.
Why it's wrong here
No ACL is required; the route-map can match all traffic.
