Syntax

[ minimum-receive-interval minRecInterval ]
[ minimum-transmit-interval minTransInterval ] ] [ multiplier multValue ]

no { ip | mpls } rsvp bfd-liveness-detection

Release Information

Command introduced in JunosE Release 8.1.0.

Description

Enables BFD (bidirectional forwarding detection) on an interface running RSVP-TE and defines BFD values to be negotiated between RSVP-TE neighbors for detection of IP data path failures. The no version disables BFD on the RSVP-TE 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

• ip—Specifies alternative keyword for compatibility with non–E Series implementations
• mpls—Specifies JunosE MPLS implementation
• 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
• 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
