Syntax

[ minimum-receive-interval minRecInterval ]
[ minimum-transmit-interval minTransInterval ] ] [ multiplier multValue ]
no ipv6 pim bfd-liveness-detection
Release Information
Command introduced in JUNOSe Release 8.0.0.
Description
Enables BFD (bidirectional forwarding detection) on an interface running PIM and
defines BFD values to be negotiated between PIM neighbors for detection of IPv6
data path failures. The
no version disables BFD on the PIM 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 neighbor multiplies by
the local router's negotiated transmit interval to determine the remote neighbor'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
