# Provisioning Pod Network Routes Pods scheduled to a node receive an IP address from the node's Pod CIDR range. At this point pods can not communicate with other pods running on different nodes due to missing network [routes](https://cloud.google.com/compute/docs/vpc/routes). In this lab you will create a route for each worker node that maps the node's Pod CIDR range to the node's internal IP address. > There are [other ways](https://kubernetes.io/docs/concepts/cluster-administration/networking/#how-to-achieve-this) to implement the Kubernetes networking model. ## The Routing Table In this section you will gather the information required to create routes in the `kubernetes-the-hard-way` VPC network. Print the internal IP address and Pod CIDR range for each worker instance: ``` for instance in worker-0 worker-1 worker-2; do gcloud compute instances describe ${instance} \ --format 'value[separator=" "](networkInterfaces[0].networkIP,metadata.items[0].value)' done ``` > output ``` 10.240.0.20 10.200.0.0/24 10.240.0.21 10.200.1.0/24 10.240.0.22 10.200.2.0/24 ``` ## Routes Create network routes for each worker instance: ``` for i in 0 1 2; do gcloud compute routes create kubernetes-route-10-200-${i}-0-24 \ --network kubernetes-the-hard-way \ --next-hop-address 10.240.0.2${i} \ --destination-range 10.200.${i}.0/24 done ``` List the routes in the `kubernetes-the-hard-way` VPC network: ``` gcloud compute routes list --filter "network: kubernetes-the-hard-way" ``` > output ``` NAME NETWORK DEST_RANGE NEXT_HOP PRIORITY default-route-081879136902de56 kubernetes-the-hard-way 10.240.0.0/24 kubernetes-the-hard-way 1000 default-route-55199a5aa126d7aa kubernetes-the-hard-way 0.0.0.0/0 default-internet-gateway 1000 kubernetes-route-10-200-0-0-24 kubernetes-the-hard-way 10.200.0.0/24 10.240.0.20 1000 kubernetes-route-10-200-1-0-24 kubernetes-the-hard-way 10.200.1.0/24 10.240.0.21 1000 kubernetes-route-10-200-2-0-24 kubernetes-the-hard-way 10.200.2.0/24 10.240.0.22 1000 ``` Next: [Deploying the DNS Cluster Add-on](12-dns-addon.md)
