Spanning tree (node.tree.*).

Fields

announce_min_interval_ms: u64

Per-peer TreeAnnounce rate limit in ms (node.tree.announce_min_interval_ms).

parent_hysteresis: f64

Hysteresis factor for cost-based parent re-selection (node.tree.parent_hysteresis).

Only switch parents when the candidate’s effective_depth is better than current_effective_depth * (1.0 - parent_hysteresis). Range: 0.0-1.0. Set to 0.0 to disable hysteresis (switch on any improvement).

hold_down_secs: u64

Hold-down period after parent switch in seconds (node.tree.hold_down_secs).

After switching parents, suppress re-evaluation for this duration to allow MMP metrics to stabilize on the new link. Set to 0 to disable.

reeval_interval_secs: u64

Periodic parent re-evaluation interval in seconds (node.tree.reeval_interval_secs).

How often to re-evaluate parent selection based on current MMP link costs, independent of TreeAnnounce traffic. Catches link degradation after the tree has stabilized. Set to 0 to disable.

flap_threshold: u32

Flap dampening: max parent switches before extended hold-down (node.tree.flap_threshold).

flap_window_secs: u64

Flap dampening: window in seconds for counting switches (node.tree.flap_window_secs).

flap_dampening_secs: u64

Flap dampening: extended hold-down duration in seconds (node.tree.flap_dampening_secs).
