Bidirectional Forwarding Detection (BFD) fails to establish a session when the transmit/receive hello intervals are set at very low values on traffic that is evaluated by a service-set. This article explains how to configure the firewall filter to skip the BFD packets from being evaluated by the service-set. If the BFD traffic does not have to be NAT'd, we can create a … [Read more...]
Recommended BFD link down detection time when OSPF graceful-restart is configured in an SRX chassis cluster
Bidirectional Forwarding Detection (BFD) is used to providing sub-second convergence times for routing protocols. But BFD detects the link down prior to receiving "Graceful Restart" message, Graceful-restart of routing protocols may not work as expected. An SRX chassis cluster is configured like below diagram and configuration. When the primary node RE (redundancy-group 0, … [Read more...]
