You can configure interface-specific EIGRP routing properties in the Interfaces tab.

Procedure

Step 1

On the EIGRP page, click the Interfaces tab.

Step 2

Click Add (add icon).

Step 3

From the Interface drop-down, choose the name of the interface to which the configuration applies.

Step 4

In the Hello Interval field, enter the interval, in seconds, between EIGRP hello packets that are sent 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, click 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. This option is not supported for devices in multi-context mode.

Step 8

Specify values for the Authentication properties:

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

  • Key Type—From the drop-down, select any one of the following key type:

    • None—To indicate that no authentication is required.

    • Unencrypted—To indicate that the key string to be used is a clear text password for authentication.

    • Encrypted—To indicate that the key string to be used is an encrypted password for authentication.

    • Auth Key—To indicate that the key string to be used 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 of up to 17 characters. For an encrypted authentication type, this field should have a minimum of 17 characters.

  • Confirm Key—Re-enter the key.
