bgp: Remove BGPv1 CRD and functionality #42278

rastislavs · 2025-10-20T09:10:27Z

In v1.18 (#38397 ) we deprecated the CiliumBGPPeeringPolicy CRD in favor of new CRDs to configure BGP (CiliumBGPClusterConfig, CiliumBGPPeerConfig, CiliumBGPAdvertisement, CiliumBGPNodeConfigOverride) introduced in v1.16 and promoted to stable API version (v2) in v1.18.

This PR finally removes the deprecated CiliumBGPPeeringPolicy CRD (also called as BGPv1) and the agent implementation handling it. It also removes its references from the documentation, as well as all references to BGPv1 vs BGPv2 - we will have only one BGP implementation from this point on.

In cilium-cli, we now use unstructured k8s client to access CiliumBGPPeeringPolicy, so that we can still test it for the previous releases and keep the deleted CRD in the sysdump for older cilium versions.

Note: contrib/containerlab cleanup will be done as a separate follow-up PR to not make this changeset even bigger.

Removed deprecated ``CiliumBGPPeeringPolicy`` CRD and its agent implementation. Use `cilium.io/v2` CRDs (`CiliumBGPClusterConfig`, `CiliumBGPPeerConfig`, `CiliumBGPAdvertisement`, `CiliumBGPNodeConfigOverride`) for configuring BGP.

Thanks for this change, much anticipated ❤️

Schema version update is required, otherwise lgtm 🚀

Schema version update is required

Bumped the schema version, thanks for the reminder!

Removes all legacy BGPv1 functionality from the BGP control plane. From this point on, there is just one BGP implementation, configurable via v2 BGP CRDs. Signed-off-by: Rastislav Szabo <rastislav.szabo@isovalent.com>

BGPv1 CRD is going to be removed, but we still need to support testing and sysdumping BGPv1 for the older releases (up to v1.18). In this change, we use generic k8s client to configure / retrieve CiliumBGPPeeringPolicy resources, so that we do not block CRD removal.

The previously deprecated CiliumBGPPeeringPolicy CRD is now removed. All users should be using BGPv2 CRDs only from this point on. Some common types from the removed CRD file are moved to the CRD files that are using them. Signed-off-by: Rastislav Szabo <rastislav.szabo@isovalent.com>

Since the BGPv1 CRDs and implemnetation have been removed, this removes all BGPv1 related documentation. Signed-off-by: Rastislav Szabo <rastislav.szabo@isovalent.com>

Documents that users should migrate to BGPv2 CRDs before proceeding with Cilium upgrade. Signed-off-by: Rastislav Szabo <rastislav.szabo@isovalent.com>
