Description
When Bidirectional Forwarding Detection (BFD) is configured in Static and Dynamic routing protocols, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to stop processing BFD packets and cause the configured routing protocol to fail over. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
