Fixes statements on the BGPConfiguration reference that a kind cluster running each release showed to be wrong.

  • The page description says the resource sets route reflectors. It sets the node-to-node mesh.
  • The name rule allowed _ and uppercase letters.
  • Deleting a node doesn't delete its node.<nodename> BGPConfiguration with the Kubernetes datastore.
  • logSeverityScreen also accepts Trace.
  • nodeToNodeMeshEnabled is a boolean, not a string.
  • asNumber strings and dotted notation work through calicoctl or the API server, but not with kubectl on native v3 CRDs (next and 3.33 only).
  • The Spec table was missing serviceLoadBalancerAggregation.
  • Changing bindMode makes the operator restart calico-node. No manual restart is needed.
  • programClusterRoutes had the wrong values, default and description (values and default in next and 3.33, description in 3.32; the field doesn't exist in 3.31).
  • prefixAdvertisements cidr takes IPv4 or IPv6.

Reproduced on v3.33.0 for next and 3.33 (native v3 CRD and API server mode), v3.32.2 for 3.32, and v3.31.7 for 3.31.

Not changed, for follow-up:

  • The [parse-duration] link has no reference definition, so it renders as literal text. A rendering bug a cluster can't show.
  • In 3.32 the asNumber change isn't applied: the old text is right in API server mode, the 3.32 default. The schema also rejects AS numbers above 2147483647 in 3.32, so "A valid AS Number" may need a range on this page and on BGPPeer. 3.33 wasn't tested for this.
