Two IP addresses from the same network assigned to routers different interfaces are not valid unless VRF is used. For example, the combination of IP address 10.0.0.1/24 on the ether1 interface and IP address 10.0.0.132/24 on the ether2 interface is invalid, because both addresses belong to the same network 10.0.0.0/24. Use addresses from different networks on different interfaces, or enable proxy-arp on ether1 or ether2.
Example
[admin@MikroTik] ip address> add address=10.10.10.1/24 interface=ether2 [admin@MikroTik] ip address> print Flags: X - disabled, I - invalid, D - dynamic # ADDRESS NETWORK BROADCAST INTERFACE 0 2.2.2.1/24 2.2.2.0 2.2.2.255 ether2 1 10.5.7.244/24 10.5.7.0 10.5.7.255 ether1 2 10.10.10.1/24 10.10.10.0 10.10.10.255 ether2 [admin@MikroTik] ip address>
