The ramblings of a computer geek
In the previous article we discovered that iBGP requires a topology and usage that ensures that our exchange of routes between routers is not stopped by the iBGP rule: “A route learned via iBGP must not be advertised to another iBGP peer.” We came across this problem in the previous article where although in normal operational the routes were being … Read more
We’ll continue to explore Internal BGP (iBGP) in this next part of our deployment. We are going to be deploying another route in the AS Blue 65001. Remember that eBGP is used between AS and iBGP is used within an AS. Be aware however, that this lab topology is flawed in terms of its configuration, but it shows up … Read more
Internal BGP (iBGP) is the next part of our deployment. We are going to be deploying two routers within one of the AS, Blue 65001. Remember that eBGP is used between AS and iBGP is used within an AS. So in this case our second router, Router B, will be linked to Router A via a single link, these … Read more
The first part is a basic deployment of BGP between two routers (Router A and Router B) with a single point to point link. In this example, each router is within its own AS (Autonomous System). Therefore any routes exchanged between each AS are eBGP (external BGP) routes. Routes exchanged within an AS are known … Read more
