Our ISP has provided us with an IP Address with a /31 Subnet.

How do I configure the MikroTik for this?

I can configure the IP Address with the /31 Subnet but when I add the Internet Route and put the Gateway address is shows as unreachable and won't connect.


Your IP -

Gateway IP -

Obviously the reason that the ISP's are giving out these addresses is to limit the number of IP Addresses required.
Works in Cisco, Juniper etc....


You need to use a /32 mask on the IP Address and set the Network Address to be the assigned gateway 


/ip address add address= interface=ether1 network=

You could also try the following

/ip address add address= interface=ether1

/ip route add dst= gateway=ether1

/ip route add dst= gateway=
