Comprehensive and Detailed Explanation

In Prisma SD-WAN routing configuration, theScopesetting on a BGP Peer (or a Static Route) controls the redistribution logic for the prefixes learned from that source.

Local Scope:If a BGP peer is configured with "Local" scope, the ION device will install the learned routes into itslocalrouting table for its own reachability, but it willnotadvertise (redistribute) these routes to other ION devices via the Secure Fabric. They remain local to the site.

Global Scope:To advertise reachability to the rest of the network, the BGP peer must be configured with"Global"scope. This tells the ION that any prefixes learned from this specific neighbor (e.g., the DC Core Switch) should be propagated across the SD-WAN overlay to remote branches. This is the critical setting for enabling branch-to-DC communication for applications hosted behind that BGP peer. Without "Global" scope, the branches would never learn the routes to the data center subnets.
