JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2023) — Question 53

You are configuring a new BGP service to your service provider. You want to ensure that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router.
Which feature achieves this requirement?

Answer options

Correct answer: D

Explanation

The IS-IS overload bit prevents the router from accepting new traffic until it has fully established its routing information, ensuring that all routes are in the table. The other options, such as BGP route reflector, IS-IS mesh group, and BGP local preference, do not directly control the timing of traffic flow based on route table readiness.
