AWS re:Invent 2018: Extending Data Centers to Cloud: Connectivity Options & Best Practices NET302

[@chetanagrawal492]

Amazingly consolidated all connectivity options together while maintaining the clear distinction on which option to be used in which situation with to-the-point explanation. I think this video stands out over all other networking videos out there from Re:Invent sessions. Loved all the diagrams as well. Great stuff!!

This is the best video on KZbin for all aws VPC and VPN connections.

45:40 Transit Gateway - I doubt it allows connecting Two VPC's with overlapping CIDR ranges. Per FAQ, it says not possible. Thoughts ?

[@38khampha]

great session, learning a lot information for networking on aws

45:43 - statement is incorrect. You cannot connect VPCs with overlapping CIDRs using TGW. It is mentioned in TGW FAQs as well. Q: Can I connect Amazon VPCs with overlapping CIDRs? A: AWS Transit Gateway doesn’t support routing between Amazon VPCs with overlapping CIDRs. If you attach a new Amazon VPC that has a CIDR which overlaps with an already attached Amazon VPC, AWS Transit Gateway will not propagate the new Amazon VPC route into the AWS Transit Gateway route table.

[@user-vk8em9nn5d]

Re-read that FAQ carefully. The VPC’s with overlapping CIDR’s cannot be routed to each other. Their routes will not propagate to the same route table. It does not say you cannot attach them both to the TGW. You can attach them to different route tables and add static routes.

Sounds like Transit VPC via CSRs is still the way to go since it offers way more flexibility and the cost of the BYOL routers pay for themselves in a few months
