Release Information
Command introduced in JunosE Release 7.1.0.
Description
Enables BFD (bidirectional forwarding detection) on an interface running IS-IS and defines
BFD values to be negotiated between IS-IS neighbors for detection of IP data path failures.
The
no
version disables BFD on the IS-IS interface.
NOTE:
BFD sessions might not be maintained when the multiplier value is 1 and
configured intervals are very short. We recommend that you do not use a multiplier
value of 1 with very short intervals.
Options
•
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
