# 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).
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].
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.
