Hello everyone, I’m trying VRRP in RouterOS 5.5, follow below my simple topology:

I’m not even “ping” on IP 192.168.0.1 from my host which have the following settings:
IP: 192.168.0.10/24
GW: 192.168.0.1

Does anyone here can help me?

Your virtual IP isn’t the same on both machines: on the master you’re using 192.168.0.1/32, on the backup you’re using 192.168.0.1/24.

Ok fewi, thanks for your reply. I see some tutorials/documents and I get one that says to me to use a /32 and others to use a /24. Can I use a /24 network in my vrrp interface?

But whatever, I can’t ping my gateway, even I set a /32 or /24. For example, this configuration doesn’t work for me:

any idea

Last config is not going to work, because virtual IP must be /32. And from configuration output I can see that you are not using v5.5 as you said in first post. It is either 4.x or early v5 RC version.
