slow Timer Interval
Parameters
value
The minimum interval, in milliseconds, between BFD control packets transmitted to and received from the peer router when BFD echo mode is enabled on both routers. The actual transmit and receive intervals are negotiated between the two routers and are equal to the greater of this value and the corresponding interval on the other router. If set, this value must be between 1000 and 30000. The default is 5000.
