We have a redundant network and its work with OSPF+MKT.

In ROUTING-FILTERS we change pref-src in every node:

/routing filters add action=accept chain=ospf-in prefix=10.0.0.0/8 prefix-length=8-32 set-pref-src=10.x.x.x

Now, when I upgrade Mikrotik to last version 6.32.2 and fastpath start to work pref-src stop to work.

Pref-src is good tool for find issues in the network ( traceroute for example ).

This is a correct behavior from fastpath?

Any alternative?

I can confirm this changed in 6.30.x. Probably best to open a support ticket on the issue.

"This problem should be already fixed. At least I cannot repeat it anymore with
v6.33rc version."

Thnks Mikrotik Team !
