Prisma Access Service Infrastructure

[Vishal_Mandliya]

What happen if  i use default BGP AS number 65534  which will be use within Prisma Access infrastructure.

Magic happens 🙂 This private ASN for peering nothing more. Better read  https://docs.paloaltonetworks.com/prisma/prisma-access/prisma-access-cloud-managed-admin/prisma-acce... as prisma access can use only private ASN even if it is not the default but for maybe complex designs multiple ASN can be used but I have not seen this.

• Enter the

  Infrastructure BGP AS

  you want to use within the Prisma Access infrastructure.

  If you want to enable dynamic routing so that Prisma Access can dynamically discover routes to resources in your remote networks and HQ or data center locations, you must use the Border Gateway Protocol (BGP). The

  Infrastructure BGP AS

  is the autonomous system (AS) number that identifies the routes through which BGP can send traffic. If you do not supply an AS number, Prisma Access uses the default AS number (65534).

  If you want to specify your own AS number, you must use an RFC 6996-compliant private AS number. Accepted formats are 4-Byte AS Plain [64512-65534],[4200000000-4294967294] or AS Dot [0.64512-0.65534], [64086.59904-65535.65534] notation.

Maybe also if you already use this ASN on your systems for internal BGP you can change the default.
