Configure EIGRP interfaces settings

Manage interface settings to optimize routing operations.

To configure EIGRP interface settings, perform these steps:

Procedure

Step 1

On the EIGRP page, click the Interfaces tab.

Step 2

Click Add (add icon).

Step 3

Select the appropriate interface from the Interface drop-down list.

Step 4

In the Hello Interval field, enter the hello interval in seconds for EIGRP packets on an interface. Valid values range from 1 to 65535. The default value is 5 seconds.

Step 5

In the Hold Time field, enter the hold time that is advertised by the device in EIGRP hello packets. Valid values range from 3 to 65535. The default value is 15 seconds.

Step 6

To enable EIGRP split-horizon on the interface, check the Split Horizon check box.

Step 7

In the Delay Time field, enter the delay time in tens of microseconds. Valid values are from 1 to 16777215.

Note

This option is not supported in multi-context mode devices.

Step 8

Specify authentication properties:

  • Enable MD5 Authentication—Check the check box to use the MD5 hash algorithm for authentication of EIGRP packets.

  • Key Type—Select one key type from the drop-down list:

    • None—Indicates that no authentication is required.

    • Unencrypted—Indicates that the key string is a clear text password for authentication.

    • Encrypted—Indicates that the key string is an encrypted password for authentication.

    • Auth Key—Indicates that the key string is an EIGRP authentication key.

  • Key ID—The ID of the key that is used to authenticate EIGRP updates. Enter a numerical key identifier. Valid values range from 0 to 255.

  • Key—An alphanumeric character string up to 17 characters. For an encrypted authentication type, this field should have a minimum of 17 characters.

  • Confirm Key—Re-enter the key.

Step 9

Click OK and click Save to save the changes.

The EIGRP interface settings that you configured are saved. The interface uses the specified hello interval, hold time, split-horizon setting, delay time, and authentication parameters for EIGRP routing operations.
