How can you route all traffic arriving on interface fe-0/0/0.0 to next-hop 10.1.1.1, regardless of other routes?

Routing all traffic arriving on a specific interface to a designated next-hop address, regardless of other routes, requires a strategic setup that enables specific traffic handling.

Using a firewall filter in combination with a routing instance and a default route effectively allows for this type of granular control. When you implement a firewall filter, you define specific matching criteria for incoming traffic, which can direct that traffic as per your specifications. In this case, the filter would match all traffic on interface fe-0/0/0.0.

By integrating this firewall filter with a routing instance, you are effectively creating a dedicated environment where you can manage how traffic flows independently from the main routing table. This means you can configure a default route that explicitly directs all matched traffic to the next-hop IP address of 10.1.1.1. This ensures that traffic is routed to this next hop, overriding other potential routes.

Thus, the combination of the firewall filter and a routing instance allows you to take control of traffic flows in a manner that is both specific and effective, achieving the goal of routing all traffic on the designated interface to the targeted next-hop without interference.
