Command introduced in JUNOSe Release 7.2.0. ipv6Address variable added in JUNOSe
Release 8.0.0.
Description
Enables BGP to determine quickly whether a BGP
neighbor is unreachable by means of a BFD protocol session to the
neighbor address or to each member of the specified peer group. The no version disables BFD liveness detection for the
neighbor or peer-group members. The default version removes the explicit configuration from the peer or peer
group and reestablishes inheritance of the feature configuration.
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
ipAddress—IP address of BGP
neighbor
ipv6Address—IPv6 address of
BGP neighbor
peerGroupName—Name of a BGP
peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group
inherit the characteristic configured with this command, unless it
is overridden for a specific peer.
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 interval
at which the local peer proposes to transmit BFD control packets to
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
multiplierValue—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
