What does the Suppressed status code indicate in the BGP table?

The Suppressed status code in the BGP table indicates that BGP knows about the network but won't advertise it. This status often occurs in scenarios where there are multiple routes to the same destination, and BGP suppresses the less preferred routes based on the routing policies and attributes such as the local preference or AS path. When a route is marked as Suppressed, it means that while the BGP process has learned about the route, it has determined that it is not the optimal path to use, so it will not share this route with other BGP peers.

This is important for BGP's operation, particularly in managing how routes are advertised throughout the network and ensuring that only the best options are shared. It helps maintain efficiency and stability in routing decisions, preventing suboptimal paths from being propagated across the network.
