Which configuration excerpt is necessary to route all traffic received on fe-0/0/0.0 to the next-hop 10.1.1.1?

The correct answer involves using a firewall filter to direct traffic to a routing instance, which subsequently contains a static route leading to the next-hop address of 10.1.1.1. This method is effective because it allows for more granular control over which types of traffic are forwarded to the next-hop. By employing a firewall filter, you can define specific criteria for the traffic, ensuring that only the relevant packets are routed accordingly.

Additionally, configuring a routing instance allows for the separation of routing domains, which can be particularly beneficial in complex network architectures. This modular approach promotes better organization and management of routing decisions.

In this instance, while other options might have elements intended to route traffic, they lack the complete functionality or specificity required for efficient routing to the desired next-hop. For example, a mere interface configuration with a policy route could force traffic to follow predetermined rules but may not provide the nuanced control that a firewall filter combined with a routing instance does. Similarly, a default route alone does not suffice, as it may lead to unpredictable routing behavior, especially if there are more specific routes applicable to traffic types.

Therefore, using a firewall filter in conjunction with a routing instance and a static route uniquely meets the requirement to ensure that all relevant traffic on the
