How to configure BGP Aggregate routes

• Prisma SDWAN ION Devices
• BGP

1. Prisma SD-WAN ION Devices  can not summarize the route in Data Center.
2. These devices can summarize the route on Branch. 
3. All the subnets in the LAN areas have to be able to summarize. The procedures are:
   1. Add summarized routes in static route on the branch to set the next hop as self
   2. For the LAN directed-connected subnet, set the scope to local so it will not be advertised to DC.
   3. If aggregate routes on Data Center, it will break the routes on DC and DC will not know which branch to send traffic to. So please do not summarize the route on DC.

Few other alternatives are as below.

• Route Aggregation at branches (as much as possible).
• Multi-hub cluster(will reduce the number of prefixes per DC cluster.
• A cloud VM to provide route aggregation.
