Custom BGP Configuration

Big picture

Use customized BIRD configuration files to enable specialized use-cases.

Concepts

In Calico Cloud, BGP is handled by BIRD. The BIRD configurations are templated out through confd. You can modify the BIRD configuration to use BIRD features which are not typically exposed using the default configuration provided with Calico Cloud.

Customization of BGP templates should be done only with the help of your Tigera Support representative.

Before you begin

Required

• Calico CNI

How to

• Update BGP configuration
• Apply BGP customizations based on how you've deployed Calico Cloud:

Update BGP configuration

Using the directions provided with the templates, set the correct values for the BGP configuration using these resources:

• BGP Configuration
• BGP Peer

Apply BGP Customizations

1. Create your confd templates.
2. Create a ConfigMap from the templates.

kubectl create configmap bird-templates -n tigera-operator --from-file=<path to directory of templates>

The created config map will be used to populate the Calico Cloud BIRD configuration file templates. If a template with the same name already exists within the node container, it will be overwritten with the contents from the config map.
