ZebOS using BGP equal-cost multi-path routing (ECMP) might not correctly update the ECMP paths when one of the paths goes down and comes back up.
ECMP does not function as desired because both available paths are not utilized. This can only be recovered by clearing the BGP connection on the affected ECMP path.
This occurs when a downstream ECMP link is disabled such that one of the two equal-cost paths becomes unavailable, and is then enable.
None.
Correctly update the ECMP route paths on update.
