What is a key difference between OSPF and BGP when used in a Palo Alto Networks firewall?
The correct answer is C. OSPF is used for internal routing, while BGP is primarily used for external routing. OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP) designed for routing within a single autonomous system (AS) - typically used inside an enterprise or campus network. BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP) designed primarily for…
Question
What is a key difference between OSPF and BGP when used in a Palo Alto Networks firewall?
Options
- ABGP does not require neighbor relationships, while OSPF does
- BOSPF operates only on IPv6, while BGP is for IPv4
- COSPF is used for internal routing, while BGP is primarily used for external routing
- DOSPF is faster than BGP in all scenarios

Explanation
OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP) designed for routing within a single autonomous system (AS) - typically used inside an enterprise or campus network. BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP) designed primarily for routing between autonomous systems, making it the protocol that powers internet routing between ISPs and large organizations. Both protocols require neighbor/peer relationships, both support IPv4 and IPv6, and BGP is not inherently faster - it is policy-driven rather than purely metric-driven. The IGP vs. EGP distinction is the fundamental and correct differentiator.
