isis bfd-liveness-detection
Syntax
[ no ] isis bfd-liveness-detection [ minimum-interval minInterval |
[ minimum-receive-interval minRecInterval ]
[ minimum-transmit-interval minTransInterval ] ] [ multiplier multValue ]
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
