To disable BFD on a specific interface while you configure BFD in CONFIGURATION mode, use the keyword disable. isis bfd all-neighbors Enable BFD on all IS-IS neighbors discovered on an interface. Syntax isis bfd all-neighbors [disable | [interval interval min_rx min_rx multiplier value role {active | passive}]] To remove all BFD sessions with IS-IS neighbors discovered on this interface, use the no isis bfd allneighbors [disable | [interval interval min_rx min_rx multiplier value role {active | passive}]] command. Parameters disable (OPTIONAL) Enter the keyword disable to disable BFD on this interface. interval milliseconds (OPTIONAL) Enter the keywords interval to specify non-default BFD session parameters beginning with the transmission interval. The range is from 50 to 1000. The default is 200. min_rx milliseconds Enter the keywords min_rx to specify the minimum rate at which the local system would like to receive control packets from the remote system. The range is from 50 to 1000. The default is 200. multiplier value Enter the keywords multiplier to specify the number of packets that must be missed in order to declare a session down. The range is from 3 to 50. The default is 3. role [active | passive] Enter the role that the local system assumes: • Active - active system initiates the BFD session. Both systems can be active for the same session. • Passive - passive system does not initiate a session. It only responds to a request for session initialization from the active system. The default is Active. Defaults Command Modes Command History See Parameters. INTERFACE This guide is platform-specific.

Parameters

disable

(OPTIONAL) Enter the keyword
