Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Detect CIDR IPv4 or IPv6 version to select nexthop **What this PR does / why we need it**: The node `InternalIP` is used as nexthop by the Kubernetes master to create routes in the Neutron router for Pods reachability. If a node has more than one `InternalIP`s, eventually IPv4 and IPv6, a random `InternalIP` from the list is returned. This can lead to the bug described in https://github.com/kubernetes/kubernetes/issues/59421 We need to check when we build a route that the CIDR and the nexthop belong to the same IP Address Family (both IPv4 or both IPv6) **Which issue(s) this PR fixes** : Fixes https://github.com/kubernetes/kubernetes/issues/59421 It is related to https://github.com/kubernetes/kubernetes/issues/55202 **Special notes for your reviewer**: This is the suggested way to fix the problem after the discussion in https://github.com/kubernetes/kubernetes/pull/59502 **Release note**: ```release-note NONE ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
