Customizing EIGRP
Step 11 Click OK.
Changing the Interface Delay Value
The interface delay value is used in EIGRP distance calculations. You can modify this value on a
per-interface basis.
To change the interface delay value, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > EIGRP > Interfaces.
The Interface pane displays the EIGRP interface configurations. The Interface Parameters table displays
all of the interfaces on the adaptive security appliance and lets you modify the settings on a per-interface
basis. For more information about these settings, see the “Configuring Interfaces for EIGRP” section on
page 23-7.
Step 2 Double-click an interface entry or choose the Interface entry and click Edit to configure the delay value
in the EIGRP parameters for an interface.
The Edit EIGRP Interface Entry dialog box appears.
Step 3 In the Delay field, enter the delay value. The delay time is in tens of microseconds. Valid values are from
1 to 16777215.
Step 4 Click OK.
Enabling EIGRP Authentication on an Interface
EIGRP route authentication provides MD5 authentication of routing updates from the EIGRP routing
protocol. The MD5 keyed digest in each EIGRP packet prevents the introduction of unauthorized or false
routing messages from unapproved sources.
EIGRP route authentication is configured on a per-interface basis. All EIGRP neighbors on interfaces
configured for EIGRP message authentication must be configured with the same authentication mode
and key for adjacencies to be established.
Note Before you can enable EIGRP route authentication, you must enable EIGRP.
To enable EIGRP authentication on an interface, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > EIGRP > Setup.
The EIGRP Setup pane appears.
Step 2 Check the Enable EIGRP routing check box.
Step 3 In the EIGRP Process field, enter the autonomous system (AS) number for the EIGRP process. The AS
number can be from 1 to 65535.
Step 4 Click the Networks tab.
Step 5 Click Add to add a new network entry.
