I want to configure Loopback on Cisco Router 7206VXR.But the error is
7206(config)#interface loopback 191
7206(config-if)#ip address 121.52.153.68 255.255.255.255 % 119.156.30.90 overlaps with GigabitEthernet0/1
------------------------
But interface gigabitethernet0/1 is
interface GigabitEthernet0/1
description ****Mainlink****
IP address 121.52.153.70 255.255.255.252
Any idea?

Hello,
the IP address displayed in the error message doesn't make any sense, the error itself obviously does,
121.52.153.68 255.255.255.255 is the IP address of the subnet used for 121.52.153.69 255.255.255.252 and 121.52.153.70 255.255.255.252, so you cannot use that address...

The Rule is a router must have each of its own interfaces on different subnets or networks (aka no sharing). So, you router cannot have 2 interfaces on same subnet/network.

.68 is z subnet add of this prefix and it does overlap.
