   What is the primary benefit of enabling BGP multipath on a router?

   • AIt increases the AS path length of routes to make them less preferred
   • BIt suppresses unstable routes to reduce route flapping
   • CIt allows the router to load balance traffic across multiple equal-cost BGP paths
   • DIt reduces the number of BGP peers required in an iBGP network

   You have two redundant paths to a destination via different providers. You want to achieve sub-second failover if the primary path fails. You have already enabled BGP fast reroute. What additional configuration is required to ensure the backup path is pre-installed in the forwarding table?

   • AIncrease the BGP hold timer to allow more time for failover.
   • BConfigure BGP multipath so both paths are installed in the forwarding table.
   • CConfigure a lower MED on the backup path.
   • DDisable BGP route damping to allow faster route updates.
