Symptom


  • A New site is onboarded to the termination node which already has an existing RN with BGP configuration
  • Post commit, the BGP connection via the existing site drops.
  • Removing the newly added site causes the original site to reestablish the BGP session.


Environment


  • Prisma Access (cloud managed)
  • BGP
  • Remote Networks (RN)


Cause


  • Local and Peer IP is configured with netmask ( /30 subnet)


Resolution


  1. Configure the EBGP local and Peer IP to use the IP address only by removing the Subnet mask.
  2. Future versions will remove the ability of adding subnet mask.
