hmm.  My installation:
- FreeBSD 13.1-STABLE #0 stable/13-n253133-b51ee7ac252c
- frr8-8.4 from packages

And I have following at FRR:
=====
B>* 172.16.30.82/32 [200/0] via 10.5.7.21, lan, weight 1, 00:00:53
   *                         via 10.5.7.22, lan, weight 1, 00:00:53
=====

at host:
=====
172.16.30.82       10.5.7.21          UGH1       18   1500        lan
172.16.30.82       10.5.7.22          UGH1       17   1500        lan
=====


So, OS-related MULTIPATH is "turned on" _and_ FRR MULTIPATH is "turned 
on" but freshports says "MULTIPATH=off: Enable multipath function"

Or some misunderstanding here?


Thanks!
