 In the realm of BGP (Border Gateway Protocol), monitoring prefixes within a BGP neighbor context is essential. It involves tracking the exchange of prefix information, which is crucial for early issue detection, preventing outages or connectivity disruptions, and troubleshooting network connectivity problems. BGP AFI (Address Family Identifier) and SAFI (Subsequent Address Family Identifier) prefixes play a vital role in routing and ensuring network reachability across diverse network environments.

 ### Monitored BGP prefixes
 
 a. **AFI-SAFI prefixes installed:**
    - These prefixes are learned from a neighbor and installed in the router's routing table. Monitoring these prefixes ensures the routing table is up-to-date and accurate, including IPv4/IPv6 prefixes, paths, and next hops.

 b. **AFI-SAFI prefixes received:**
    - These prefixes are advertised by a neighbor in its update messages. Monitoring them helps detect inconsistencies between advertised and installed prefixes in the routing table.

 c. **AFI-SAFI Prefixes Sent:**
    - These prefixes are the ones that a router communicates to its neighbor in its update messages. Monitoring these prefixes provides insight into the network destinations that the router actively announces to other nodes in the network. Understanding these announcements is essential for comprehending the router's routing decisions and its impact on network reachability.
