FIB (Forwarding Information Base) optimization: Protocol routes are downloaded to the RIB (Routing Information Base), which then downloads them to the FIB. Initial route optimization eliminates redundant next-hop entries.
Hardware table optimization: Routes with common prefixes are stored in separate tables. The Longest Exact Match (LEM) table handles common prefixes. The Longest Prefix Match (LPM) table retains enough headroom to accommodate route entries that are added.
