What Is iBGP? Interior Border Gateway Protocol (iBGP) is a part of the Border Gateway Protocol (BGP) family, which is used for exchanging routing information within a single Autonomous System (AS). An AS is essentially a large network or group of networks under a common administration, often belonging to an organization or an internet service provider. Here are… Read More »
What is eBGP? External Border Gateway Protocol (eBGP) is a BGP term or process used when referring to BGP peers or neighbours that are in a different Autonomous System and Number (ASN).In other words, eBGP is used to exchange route information between different autonomous systems. When only one link connects two autonomous systems, the IP addresses of the connected interfaces are… Read More »
How To Authenticate MD5 for BGP Peers. BGP (Border Gateway Protocol) Peers MD5 Authentication is a security feature used in BGP, the protocol that manages how packets are routed across the internet through different networks (autonomous systems). This feature enhances security by establishing a secure connection between BGP peers (routers) using MD5 (Message Digest 5) hashing. Key Points… Read More »
The Border Gateway Protocol (BGP) is a complex, advanced distance routing protocol utilized primarily for exchanging routing information between major Internet Service Providers (ISPs) and larger client sites. It uses the Best Path Selection Algorithm to choose efficient routes, supporting the complexity of the public internet.
This post explains how to configure BGP using loopback addresses, especially with iBGP. It discusses this configuration within the context of RouterHQ and BranchOffice from AS 556.
