Do the following options make vnet to be transitive ? thanks !!

Hello Gongya Yu , Thanks for your question. No. Transitive peering is not supported. Vnets are not transitive. If you peer VNetA to VNetB and you peer VNetB to VNetC, VNetA and VNetC do not get peered automatically. You must manually peer VNetA to VNetC.

@Gongya Yu ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I see akinbade abiola has answered your queries.

As mentioned in the FAQ, VNETs are not transitive.**

The option you see above simply means Azure will simply "allow" traffic across VNETs even though it has not been originated in either of those VNETs.

But it will not take care of the routing part

i.e., if customers manually configure the routing - Azure allows it

You can make use of Azure Firewall to forward traffic.

Kindly let us know if we can be of any further assistance here.

Thanks,

Kapil
