Definition
Border Gateway Protocol (BGP) (โปรโตคอลเกตเวย์ชายแดน (BGP)) Hard Skill
Border Gateway Protocol (BGP) is the standardized exterior gateway protocol used to exchange routing information between autonomous systems on the internet, enabling data routing decisions based on path, network policies, and rule-sets.
Expertise Level
Level 1
Basic
1. Understands the fundamental purpose and function of BGP.
2. Can identify key BGP components like AS numbers and neighbors.
3. Knows basic BGP message types and their roles.
Level 2
Intermediate
1. Configures and manages BGP sessions between autonomous systems.
2. Implements basic routing policies and prefix filtering.
3. Troubleshoots common BGP issues like route flapping and session failures.
Level 3
Advanced
1. Designs complex BGP architectures for large-scale networks.
2. Implements advanced routing policies using route-maps, communities, and attribute manipulation.
3. Optimizes BGP performance and ensures high availability through redundancy and failover strategies.
