Title: OPNsense ECMP routing

Hello!

I'm wondering does latest version (21.1.X) of OPNsense support ECMP (equal cost multipath) routing with FRR?

With my lab devices (20.7.5) I tried to simulate it using OSPF and was able to see two paths in FRR (vtysh -> sh ip ro ospf), however netstat -rnl4 shown completely different story (only one of the paths is actually installed into BSD routing table)

I've found that from almost 2 years ago - https://forum.opnsense.org/index.php?topic=12815.0 which was not positive at all during that time...

Regards,
Plamen

No, AFAIK the radix implementation in FreeBSD is quite error prone. In FreeBSD 13 they have a new and more stable approach, but this will need some time

Thanks for confirming.
