Customizing EIGRP
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:
Detailed Steps
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:
Command Purpose
Step 1 interface phy_if
Example:
hostname(config)# interface phy_if
Enters interface configuration mode for the interface on which
you are changing the delay value used by EIGRP.
Step 2 delay value
Example:
hostname(config-if)# delay 200
The value argument entered is in tens of microseconds. To set the
delay for 2000 microseconds, you enter a value of 200.
To view the delay value assigned to an interface, use the show
interface command.
