Question


Why are OSPF routes not seen on the Passive Firewall?

Environment


  • Any Palo Alto Firewall.
  • Any PAN-OS.
  • High Availability Active/Passive.

Answer


In a High Availability Active-Passive Configuration, the Passive device does not forward traffic and so does not form OSPF adjacency with neighbor. Hence the OSPF routes will not be present in the routing table of Passive firewall.

Additional Information


This is an expected behavior.
