Routing entry "0.0.0.0/0" is displayed when checking Routing information of Service Connections/Remote Networks in Prisma Access

• The routing entries on Prisma Access  SC CAN and RN SPN can be accessed via GUI: Panorama > Cloud Services > Configuration > Service Setup > Service Operations > Troubleshooting Commands > Routing Information.
• Here one may see routing entries for Destination:0.0.0.0/0, Nexthop:0.0.0.0/0, and Flags:

• Panorama Managed Prisma Access
• Cloud Managed Prisma Access
• SC CAN  (Service connection, also known as a Corporate Access Node)
• RN SPN (Remote Network Security Processing Node)

• This entry is be displayed when "Advertise Default Route" for BGP has been enabled in the peer site settings configured on the CAN/SPN.
• Panorama > Cloud Services > Configuration > Service Setup > Service Operations > Onboarding 

1. This behavior is expected when "Advertise Default Route" has been enabled.
2. With this setting Prisma Access Firewalls create a Redistribution Rule of 0.0.0.0/0 internally.
3. Therefore, the corresponding routing entry will be displayed for the internal use.
4. It is not possible to hide this routing entry when "Advertise Default Route" is enabled.

This behavior is consistent with the On-Prem FW described under Understanding routing flag.
