# BGPAdvertisement is used to advertise address pools to the BGP peer. Specific pools can be listed to be advertised.

# Local BGP Advertisement specifies that the IP specified in the address pool will be used as remote source address for traffic entering your cluster from the remote peer.
|
|
# When using this option, be sure to use a subnet and routable IP for your address pool.
|
|
# This is good: 10.0.0.10/24. This is also good: 10.0.0.129/25. This is bad: 10.0.0.0/24. This is also bad: 10.0.0.128/25.

# In this example, 10.0.0.10 will be used as the remote source address.

|
|
# The no-advertise community is set on the local advertisement to prevent this route from being published to the BGP peer.
|
|
# Your aggregationLength ideally is the same size as your address pool.
