ospf discarding hallo packet

RouterOS Forwarding Protocols
1

Hi i have setup ospf by just adding 172.23.1280/24 as backbone. My whole network is cut into smaller subnets.

One one router i get this message in the logs,

route,ospf,info Discarding Hello packet: mismatch in network mask 
14:06:54 route,ospf,info     mine=255.255.255.252 
14:06:54 route,ospf,info     remote=255.255.255.248 
14:06:54 route,ospf,info     source=172.23.128.2 
14:07:04 route,ospf,info Discarding Hello packet: mismatch in network mask 
14:07:04 route,ospf,info     mine=255.255.255.252 
14:07:04 route,ospf,info     remote=255.255.255.248 
14:07:04 route,ospf,info     source=172.23.128.2

What can i do?
thanx in advanced

I would say that was pretty obvious.
The log tells you that your end of the link has a different subnetmask than the router at the other end of the link. Your end is a /30 while the remote end is a /29.

The other end is actually /28. Looks like there is no solution. The log is full of it.

PS: I do know what it mean i want to know how to get rid of it without makeing both subnets the same

Sorry my bad. forgot to change remote address subnet from 29 to 30
