Description
Enable BFD session damping to dampen excess flap notifications from a BFD session that is going up and down repeatedly. BFD session damping using a merit system where each flap adds to a merit value, and once a BFD session reaches the configured merit value, notifications will be dampened. The merit value decreases by half after a configured time period, and when it falls below a configured threshold, BFD state change notifications will resume.
BFD session damping happens independently on each router locally, so BFD session configuration values should match on both ends of a BFD session to ensure consistent behavior.
Options
| half-life-interval |
Time duration before the accumulated merit value for a BFD session is reduced by half.
|
| increment |
Increments applied to merit value for every flap
|
| max-suppress-time |
Maximum amound of time time a BFD session can be suppressed no matter how unstable it has been prior to this period of stability.
|
| reuse |
Maximum merit value that will allow a suppressed BFD session to start notifications again.
|
| suppress |
Minimum merit value that will start suppressing BFD notifications.
