Enabling BGP routing

To support dynamic route advertisement and integration with external network infrastructure, you can enable Border Gateway Protocol (BGP) routing for your cluster as a cluster administrator.

As a cluster administrator, you can enable OVN-Kubernetes BGP routing support for your cluster.

Enabling Border Gateway Protocol (BGP) routing

To allow external network integration and route advertisement on supported infrastructure, you can enable Border Gateway Protocol (BGP) routing for your cluster by configuring the cluster network to use an FRR-based dynamic routing provider.

As a cluster administrator, you can enable BGP routing support for your cluster on bare-metal infrastructure.

If you are using BGP routing in conjunction with the MetalLB Operator, the necessary BGP routing support is enabled automatically. You do not need to manually enable BGP routing support.

Prerequisites

  • You have installed the OpenShift CLI (oc).

  • You are logged in to the cluster as a user with the cluster-admin role.

  • The cluster is installed on compatible infrastructure.

Procedure

  • To enable a dynamic routing provider, enter the following command:

    $ oc patch Network.operator.openshift.io/cluster --type=merge -p '{
  "spec": {
    "additionalRoutingCapabilities": {
      "providers": ["FRR"]
    }
  }
}'
