Restrict access to loopback using ACL

[ramcm.rr]

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
