Question:
When a device learns multiple routes to a specific network, it installs the route with :

• Longest bit Match (highest subnet Mask)
• lowest AD
• lowest metric
• equal load balancing

Explanation: Making a forwarding decision actually consists of three sets of processes: the routing protocols, the routing table, and the actual process which makes a forwarding decision and switches packets. The longest prefix match always wins among the routes actually installed in the routing table, while the routing protocol with the lowest administrative distance always wins when installing routes into the routing table.
