Custom route advertisements
With custom route advertisements, you choose which routes Cloud Router advertises to your on-premises router through the Border Gateway Protocol (BGP).
You can specify route advertisements on the Cloud Router or for each BGP session. If you specify advertised routes on the Cloud Router, they apply to all BGP sessions on the Cloud Router. If you specify route advertisements on a BGP session, those advertisements replace the Cloud Router advertisements.
If you configure IPv6 custom route advertisements on a Cloud Router, the IPv6 routes are advertised only in BGP sessions where IPv6 is enabled (Preview).
For more information about route advertisements and the default behavior, see Route advertisements in the Cloud Router overview.
