RouterOS no longer responds to ff02::1?

Mon Feb 12, 2018 11:49 pm

I have used link-local addresses to connect to routerboards without having to use a serial console while configuring them.
(This is helpful for things that can't be done with a console, such as routing filters with multiple types of routes to match. Everything, even exports, say you can do protocol=connect,static, but you will get an error if you try that on the console.)

I would discover the link local address by pinging like this:

ping ff02::1 -I <nameofinterface>

And then look at the address that responds that is NOT my computer. Then I could connect with something like [fe80::2eec:3adf:e95f:a44%interfacename]

This worked great, but in recent versions, I get no ICMP replies when pinging the multicast address ff02::1. Is this a bug? A "feature"? Something I can fix with configuration? (but that kind of defeats how I use this).

I just tested this between my Mac laptop and my RB750Gr3 running 6.41.1. I had no problem connecting to the link local address on the MikroTik.

I also see the link local address from the MikroTik when I ping ff02::1%en0

I have lots of stuff in the same L2 domain and lots of stuff is responding

Something seems wrong with yours maybe.
