Hello All,
I have tried to restrict access to loopback interface using ACL's with no luck. Does anyone know how this can be done?
Thanks,
Ram

The loopback is a "special" interface.
To limit connectvity you should look into restricting via the Control Plane - BEWARE you break everything if configured incorrectly. Read the below VERY carefully.

Andrew is correct.
Think "why" you're doing before doing it.

I used management plane protection and it works great!
control-plane host
management-interface FastEthernet4 allow ssh snmp
