There have been reports of instability with some routing scenarios since this was enabled. We shouldn't take any action on it until after base is shifted to 12-STABLE. If problems persist then we may want to back this out (and #9544)

This requires RADIX_MPATH in the kernel which proved to be too unstable, thus had to be removed. See #9544.
We will revisit it in the future.

Is that an option for usage in 2.7/23.01 and foward? With the new FBSD14 base would it be possible to revisit this? Multipath in FRR would be a huge gain when builing e.g. a multi-VPN router via various WAN uplinks to "bond" them together for a better throughput. Currently that works OK'ish with the loadbalanced gateway group feature but OSPF+MPATH should be better and faster to react to changes in that concern.

Builds based on FreeBSD 14 (including 23.01 and snapshots of 2.7.0) have ROUTE_MPATH enabled in the kernel and it's active already. You can check the value of net.route.multipath. If it's 0 then it's inactive, 1 is active.
While that is in the kernel, we haven't yet enabled it in FRR for this release, but may consider it post-release in development snapshots where it can be tested with less danger.
