Suggested answer: C

Explanation:

Graceful Restart (GR) is a feature that allows a router to maintain forwarding even when the routing process (e.g., the rpd process in Junos) is restarting, minimizing disruption to the network.

Step-by-Step Breakdown:

Graceful Restart Function:

During a GR event, the forwarding plane continues to forward packets based on existing routes, while the control plane (rpd process) is restarting. This prevents traffic loss and maintains routing stability.

Minimizing Disruptions:

GR is particularly useful in ensuring continuous packet forwarding during software upgrades or routing protocol process restarts.

Reference:

Graceful Restart in Junos: GR ensures high availability by maintaining forwarding continuity during control plane restarts, enhancing network reliability.
