Transit VPC Google cloud networks are easy to decipher with a little help from our experts. 

At Bobcares, we offer solutions for every query, big and small, as a part of our Google Cloud Support Services.

Let’s take a look at how our GCP Support Team is ready to help customers with understanding more about transit VPC Google cloud networks.

What is Transit VPC Google cloud network?

Suppose that we have only one connection on the premises like interconnect or a VPN tunnel, between the on-premises network and our VPC network. We may want to share the connection with other VPC networks without having to go through the trouble of recreating an on-premises connection for each VPC network.

In this scenario, we can set up a transit network. In other words, this will allow other networks to use the on-premises network without running into any further trouble. Furthermore, while peer networks can use the on-premises connection, they cannot route traffic to another peer via the transit network.

Today, our Google Cloud Experts are going to demonstrate how to set up a transit network. In this scenario, let’s assume there are three VPC networks, namely, network-1, network-2, and network-3. Here, network-1 is peered with the other two networks. Moreover, the three networks import and export custom routes while network-1 acts as the transit network, as the VPN tunnel is here.

Here are a few of the features of the VPC Transit network:

• The Cloud router in charge of the routes for the tunnel automatically presents subnet UP address ranges of the subnets in network-1 by default.
• Cloud Router will automatically install routes to on-premises destinations as custom dynamic routes in network-1.
• We have to add the subnet IP address ranges for subnets in network-2 and network-3 via custom route advertisement configuration on the Cloud Router.
• They exchange custom dynamic routes via VPC network peering to network-2 and network-3.

About Encryption in VPC Transit Network

Google relies on several encryption methods, user-configurable as well as default methods for the data in transit. Additionally, the method in use usually depends on the OSI layer, the infrastructure’s physical components, and the type of service. Moreover, Google has several open-source projects that support encryption in transit as well as data security over the internet.
