no address { ipAddress | unnumbered interfaceType interfaceSpecifier }
bfd-liveness-detection

#### Release Information

Command introduced in JunosE Release 8.0.0.

#### Description

Enables BFD (bidirectional forwarding detection) on an interface running RIP and defines BFD values to be negotiated between peers for detection of IP data path failures. The no version disables BFD on the RIP interface.

#### Options

- ipAddress—Address of IP interface where RIP will be run
- unnumbered—Specifies that RIP will be run on an unnumbered interface
  - interfaceType—Interface type; see Interface Types and Specifiers
  - interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers
- minInterval —Minimum proposed transmit interval and required receive interval for BFD control packets; has the same effect as configuring the minimum receive interval and the minimum transmit interval to the same value; number in the range 100–65535 milliseconds—for ES2 4G LM only, the range is 10–65535 milliseconds; default value is 300 milliseconds
- minRecInterval—Minimum interval at which the local peer must receive BFD control packets sent by the remote peer; number in the range 100–65535 milliseconds—for ES2 4G LM only, the range is 10–65535 milliseconds; default value is 300 milliseconds
- minTransInterval—Minimum proposed interval between BFD control packets sent by the local peer; number in the range 100–65535 milliseconds—for ES2 4G LM only, the range is 10–65535 milliseconds; default value is 300 milliseconds
- multValue—Detection multiplier value that the remote peer router multiplies by the local peer's negotiated transmit interval to determine the remote peer's BFD liveness detection interval; equal to the number of BFD packets that can be missed before the BFD session is declared down; number in the range 1–255; default value is 3
