Hello, Hello, I tried to configure and set up a connection between two vwans. Below are the design details. Two Vnets in two different regions (Vnet-A and Vnet-B). VNEt-A: 10.40.0.0/24 | Vnet-B: 10.60.0.0.0/24 2. Two Virtual hubs (vHu-A: 192.168.10.0/24 and vHub-B: 192.168.20.0) 3. Configured VPN sites under the HUB. Configured the S2S rather than Express route as this is Lab scenario. Created a GW and also LNG as suggested by Co-Pilot. Configured Route table and associated as well as Propagated. Attached are the screen shots as I am getting " Instance0:Notconnected and Instance1:NotConnected' Please provide me a solution so that I can complete the Lab and also the connectivity part. I am missing something which is stopping me to configure the connection. "Connected Hub: Not connected" Thanks in advance, Raja V

Hello,

I tried to configure and set up a connection between two vwans. Below are the design details.

Two Vnets in two different regions (Vnet-A and Vnet-B).

VNEt-A: 10.40.0.0/24 | Vnet-B: 10.60.0.0.0/24 2. Two Virtual hubs (vHu-A: 192.168.10.0/24 and vHub-B: 192.168.20.0) 3. Configured VPN sites under the HUB.

Configured the S2S rather than Express route as this is Lab scenario. Created a GW and also LNG as suggested by Co-Pilot.
Configured Route table and associated as well as Propagated. Attached are the screen shots as I am getting " Instance0:Notconnected and Instance1:NotConnected'

Please provide me a solution so that I can complete the Lab and also the connectivity part. I am missing something which is stopping me to configure the connection.

"Connected Hub: Not connected"

Thanks in advance,

@Raja Sheker Vuttham

Thank you for reaching out.

Can you share a network diagram of your set-up here? it will help troubleshoot the issue.

Meanwhile you can also check if you selected the supported IPsec policy in your set-up here. Setting up diagnostic logging can also help troubleshoot the issue. Thanks

@ChaitanyaNaykodi Unfortunately, I deleted the Resource group. Anyhow I will give a try tomorrow again and will provide the Network Diagram /topologyg.

Thanks,

I hope you have understood the issue. What shall be implemented in between so as to let the connections Up and running. Is that the Routing part or something else.

Thanks

I changed the design and implemented the below:

Two Vnets:

vnet-a and Vnet-b

vnet-a: 10.40.0.0/24 (central India)

vnet-b: 10.50.0.0/24 (South India)

virtual hub: 192.168.10.0/24

All I need to establish the connectivity between the two vnets using the vwan in between and also S2S VPN.
As this is a Lab, I am considering the vnet-a as "On-premises "and vnet-b as "my envi"

Attached is the topology after configuration.
Everything is success and provisioned, but VPN connectivity is still failing.

Thank You,

Raja V
