Configuration Tab
The Configuration tab of the Loopback Interface Management window consists of a single area,
Configuration. The Configuration area provides the following information:
•
Loopback Interface Table—Lists the loopback interfaces that have been deployed on the device. The
unique identifier of a Loopback interface in the device is displayed in this table:
•
Description—Description of the interface corresponding to the index selected in the Loopback
Interface Table.
The following subareas are available within the Loopback area on the Configuration tab of the Loopback
Interface Management window:
•
Layer 3
•
Routing Protocol
•
Loopback
Layer 3
The Layer 3 subarea provides the following information:
•
IP Address—IP address of the interface. A value of 0.0.0.0 indicates that no IP address has been
configured on the interface.
•
Netmask—IP subnet mask of the interface. The value of the mask is an IP address with all the
network bits set to 1 and all the host bits set to 0.
Routing Protocol
The Routing Protocol subarea contains the following information:
•
ISIS Area Tag—Identifies the IS-IS routing area that the Loopback participates in. If multi-area
IS-IS is configured on the device, the IS-IS area must be named. Otherwise, this value may be an
implicit null tag. This attribute is only valid if the IS-IS Enabled attribute is true (1).
•
ISIS Enabled—Indicates whether or not IS-IS routing is enabled on the interface. IS-IS routing can
only be enabled if the loopback interface has been assigned an IP address.
Loopback
The Loopback subarea contains the following information:
•
Loopback Index—Unique identifier of a new loopback interface to be deployed on the device.
•
Create—Deploys on the managed device a loopback interface identified by the Loopback Index
field. The newly added loopback interface will be displayed in the Loopback Interface Table.
•
Remove—Removes the loopback interface identified by the Loopback Index field from the device.
