Explanation

Configure summary-address level-2 64.45.52.0 0.0.3.255 on R2: This command summarizes the routes at Level-2 on R2. It helps to reduce the number of specific routes advertised toward Level-2 routers, which in turn optimizes R4's routing table and memory Configure summary-address 64.45.52.0 255.255.252.0 level-1 on R3: This creates a summary route for Level-1, consolidating routes that are more granular into a This reduces route advertisements in the Level-1 domain and minimizes routing table size. The excessive routes and memory consumption issue is addressed through route summarization. Summarizing routes: - Reduces the number of routes that need to be stored. - Optimizes router performance and memory usage. - Ensures only essential routes are advertised into the routing domains (Level-1 and Level-2).
