bgp PrefVal

BGP (Border Gateway Protocol) PrefVal refers to the preference value assigned to a BGP route by a BGP router. The preference value is used to determine the best path among multiple routes to the same destination. When a BGP router has multiple paths to a destination, it selects the path with the highest preference value as the best path.

The preference value is a locally significant value and can be set by the BGP router itself or by a BGP policy configured on the router. The default preference value for BGP routes is 100. However, different routing protocols may also have their own preference values, which can affect the BGP path selection process.

In summary, BGP PrefVal is an important parameter that BGP routers use to determine the best path among multiple routes to a destination. The higher the preference value, the more preferred the route is.
