  • BGP Configuration Example 2: EBGP Using Loopback Interfaces

    BGP Configuration Example In the last tutorial “BGP configuration example : EBGP Peering“, we configured an EBGP peering between two routers using their physical interface IP addresses. In this BGP configuration example, we’ll use loopback interfaces for BGP peering. We prefer loopback interfaces when there are multiple paths between peers because they provide more stability…

  • BGP Configuration Example 1: EBGP Peering

    BGP Configuration Example: In the previous chapter, you learned about BGP’s peering process and states. In this BGP configuration example , you will learn how to configure BGP with two Cisco routers, check the BGP peering status, and understand different BGP show commands. We’ll provide step-by-step instructions to set up an EBGP peering, verify the…

  • BGP Protocol Peering and States

    BGP Peering Process: The BGP peering process involves several steps that BGP routers take to create and maintain a secure and reliable connection for exchanging routing information. This process goes through various stages, known as “BGP states.” In this tutorial, we will discuss the step-by-step process BGP follows to complete the peering. This process forms…
