suresh Main Differences Between EBGP and IBGP
External Border Gateway Protocol (EBGP) and Internal Border Gateway Protocol (IBGP) are two types of BGP protocols used in routing. The main differences between EBGP and IBGP lie in their use cases and routing behavior.
EBGP (External BGP)
EBGP is used between different autonomous systems. It is typically used to connect to external networks or different service providers. EBGP routers are usually directly connected to routers in other autonomous systems. The key characteristic of EBGP is that it carries routing information between different autonomous systems, making it suitable for inter-domain routing.
IBGP (Internal BGP)
IBGP is used within the same autonomous system. It is typically used to distribute routing information between routers within the same organization or network. IBGP routers are usually internal routers that need to communicate with each other to maintain consistent routing tables. Unlike EBGP, IBGP does not carry external routing information.
Overall, the main difference between EBGP and IBGP is the scope of their application: EBGP is used for inter-domain routing, while IBGP is used for intra-domain routing within the same autonomous system.
