PCNSE Exam - Question 533


An engineer manages a high availability network and requires fast failover of the routing protocols. The engineer decides to implement BFD.

Which three dynamic routing protocols support BFD? (Choose three.)

Show Answer
Correct Answer: ACD

Bidirectional Forwarding Detection (BFD) can be used with various dynamic routing protocols to provide fast failover times. BFD supports OSPF, OSPFv3 virtual links, and BGP. It does not support IGRP, as it is an older Cisco-proprietary protocol, nor RIP, which typically relies on slower convergence methods. Therefore, the correct routing protocols that support BFD are OSPF, OSPFv3 virtual links, and BGP.

Correct is ADE In addition to BFD for static routes, the firewall supports BFD for the BGP, OSPF, and RIP routing protocols. https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-networking-admin/bfd/bfd-overview/bfd-for-dynamic-routing-protocols

"In addition to BFD for static routes, the firewall supports BFD for the BGP, OSPF, and RIP routing protocols." "The firewall does not support BFD on an OSPF or OSPFv3 virtual link." IGRP is a Cisco-proprietary protocol that is not mentioned in the Palo Alto Networks documentation. https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-networking-admin/bfd/bfd-overview/bfd-for-dynamic-routing-protocols
