Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set routing-instances dept-fwd routing-options interface ge-0/0/0.0
Why it's wrong here
Interfaces are assigned to routing instances, but instance-type must be defined first.
- ✗
set routing-instances dept-fwd instance-type virtual-router
Why it's wrong here
Virtual-router is too heavy for simple FBF and runs separate routing protocols.
- ✗
set routing-instances dept-fwd instance-type l3vpn
Why it's wrong here
L3VPN requires route targets and RD configuration, which is unnecessary for basic FBF.
- ✓
set routing-instances dept-fwd instance-type forwarding
Why this is correct
The 'forwarding' instance type is specifically designed for filter-based forwarding (FBF) applications.
