How to configure routing VPN s2s with many sites and many p2s

Przemek Zembrzuski 0

Hi,

I have 10 branches that must communicate each other. Is possible to configure VPN s2s with bgp to accomplish this and how to add some p2s vpn connections that can reach branches networks?

Is better to do this with the same ASn for on-premise router or each with different AS?

Thank you for reaching out.

Just to confirm my understanding. You wish to connect the 10 branches via s2s VPN to Azure and add P2S VPN to the same VPN Gateway so that they can reach the branch networks?

Can you please confirm my understanding above? before I suggest a solution here. Thank you!

Hi,

You can try to deploy vWAN to achieve this, which supports upto 30 connections. Reference: https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-faq#how-is-virtual-wan-different-from-an-azure-virtual-network-gateway

You can use the same ASN to connect, as long as there are no IP overlap, you should be good to connect all 10 branches to Azure via S2S over BGP.
