# BGPAdvertisement tells MetalLB to announce allocated Service addresses as
# routes to the MikroTik peer defined in bgppeer.yaml. Unlike Layer 2 mode,
# the workers do not need an interface inside 10.10.60.0/24: the router learns
# that each allocated address is reachable through the Kubernetes nodes.
#
# `aggregationLength: 32` advertises only addresses that a Service actually
# owns, as individual IPv4 host routes. Advertising the whole /24 would make
# the router send every address in the pool toward the cluster, including
# unallocated ones.
#
# Sync wave 1 defers this custom resource until the MetalLB chart's CRDs and
# controllers from wave 0 are available.
