Outbound path selection controls how MTRP chooses among direct-neighbor candidates.

Supported options:

• FIRST_VALID: keep the first usable candidate found
• LAST_IN: prefer the most recently seen candidate
• BEST_METRIC: prefer the candidate with the lowest metric
• MOST_RELIABLE: prefer the candidate with the best reliability score

Learned route selection controls how MTRP chooses among forwarding candidates.

Supported options:

• FIRST_VALID: keep the first usable learned candidate
• LAST_UPDATED: prefer the most recently updated candidate
• BEST_METRIC: prefer the candidate with the lowest metric
• STICKY_BEST_METRIC: keep the current preferred route until a meaningfully better route appears

STICKY_BEST_METRIC uses:

• improvement delta
• hold-down timer
• preferred-route state

This reduces unnecessary route flapping.
