Table 161: Oam Configuration Details (continued)
Task
Enable Bidirectional
Forwarding Detection (BFD)
for all of the MPLS LSPs or
for just a specific LSP.
Specify the threshold for the
adaptation of the detection
time.
Configure route and
next-hop properties in the
event of a BFD protocol
session failure event on an
RSVP label-switched path.
Specify the minimum
transmit interval for failure
detection.
Your Action
1. Click Bfd Liveness Detection next to Oam.
2. In the Comment box, enter the comment.
3. From the Version list, select the BFD version to be used for
detection.
4. From the Minimum Interval list, select the minimum transmit
and receive interval.
Range: 1 through 255,000 milliseconds
5. From the Minimum Receive Interval list, select the minimum
receive interval.
Range: 1 through 255,000 milliseconds
6. From the Multiplier list, select the detection time multiplier.
Range: 1 through 255
Default: 3
7. Select the No Adaptation check box to disable BFD adaptation.
1. Click Detection Time next to Bfd Liveness Detection.
2. In the Comment box, enter the comment.
3. From the Threshold list, select the threshold for detecting the
adaptation of the transmit interval.
1. Click Failure Action next to Bfd Liveness Detection.
2. In the Comment box, enter the comment.
3. Click Teardown next to Failure Action.
4. Select one of the following:
teardown—when a BFD session fails for an RSVP LSP, the
associated LSP path is taken down and resignaled
immediately.
make-before-break—when a BFD session fails for an RSVP
LSP, an attempt is made to signal a new LSP path before
tearing down the old LSP path.
a. In the Comment box, enter the comment.
b. From the Teardown Timeout list, select the time in
seconds.
1. Click Transmit Interval next to Failure Action.
2. In the Comment box, enter the comment.
3. From the Minimum Interval list, select the minimum interval
at which the local router transmits hello packets to the neighbor
with which it has established a BFD session.
Range: 1 through 255,000 milliseconds
4. From the Threshold list, select the threshold for detecting the
adaptation of the transmit interval.
Range: 0 through 4,294,967,295 milliseconds
