Examples
The following example shows how to configure the BFD slow timers value to 14,000 milliseconds:
Device(config)# bfd slow-timers 14000
The following output from the show bfd neighbors details command shows that the BFD slow timers value
of 14,000 milliseconds has been implemented. The values for the MinTxInt and MinRxInt will correspond
to the configured value for the BFD slow timers. The relevant command output is shown in bold.
