I have noted that DDNS updates occer error while ECMP in ROSv7.
Is there any solution to it ?
It’s pretty hard to say anything at all without knowing how, when, which DDNS provider, RouterOS 7 version, network topology, etc..
More details are in fact needed. e.g. if ECMP selects a route without a public IP, DDNS isn’t going to work. Among other potential reasons. Without no logs, config, diagram, etc… really hard to know.
