- Checking when the interface is up, related connected network is not installed in BGP, as connected networks are not redistributed into BGP

- Prisma Access
- PANO-OS 10.2.4
- PANO-OS 10.2.10

• App Acceleration was introduced on 10.2.8 onwards
• In Prisma Access service interfaces for App Accel: GPGW ethernet1/2 ; and RN ethernet1/3
• saas-agent and saas-infra versions add service interfaces in PANOS 10.2.4 even though App Accel is not supported; also in later versions 10.2.10+ even if the customer has no App Accel license the service vNICs are added

There is no services affected as the connected routes derived from the service vNICs are not propagated into BGP
