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
