  1. allow network access and forward traffic is enabled in all vnet.
  2. NIC card are enabled with IP forward traffic

    Hello @Karthick G ,

    Transitive peering is not supported in Azure which means if you peer VNet1 to VNet2 and you peer VNet1 to VNet3, VNet2 and VNet3 are NOT automatically peered. You must peer VNet2 and VNet3 to establish communication between VNet 2 & 3.
    Please refer : https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq#if-i-peer-vneta-to-vnetb-and-i-peer-vnetb-to-vnetc-does-that-mean-vneta-and-vnetc-are-peered

    You can find the connectivity options available for Azure resources in below article:

    Hope this helps!
