Comparing IGP and BGP Data Center Convergence
A LinkedIn article claims iBGP designs may slow convergence due to route reflectors, but in simple leaf-and-spine fabrics, the routing protocol choice is irrelevant.
MAIN POINTS
- A Thought Leader compared IGP and BGP convergence in data center fabrics.
- The article suggests iBGP designs need route reflectors, potentially slowing convergence.
- The claim about slower convergence is questioned in the blog post.
- In simple leaf-and-spine fabrics, routing protocol choice is deemed unimportant.
TAKEAWAYS
- iBGP designs might involve additional processing due to route reflectors.
- The blog post challenges the claim of slower convergence with iBGP.
- Understanding routing protocol impact is crucial for data center fabric design.
- Simple network designs may not be affected by routing protocol differences.
