Configuring EIGRP Route Authentication

EIGRP route authentication provides MD5 authentication of routing updates from the EIGRP routing
protocol to prevent the introduction of unauthorized or false routing messages from unapproved sources.
Beginning in privileged EXEC mode, follow these steps to enable authentication:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
no shutdown
Step 4
ip authentication mode eigrp autonomous-system md5
Step 5 ip authentication key-chain eigrp autonomous-system
key-chain
Step 6 exit
Step 7 key chain name-of-chain
Step 8 key number
Step 9 key-string text
Step 10
accept-lifetime start-time {infinite | end-time | duration
seconds}
Step 11 send-lifetime start-time {infinite | end-time | duration
seconds}
Step 12 end

Purpose
Display which interfaces EIGRP is active on and
information about EIGRP relating to those interfaces.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the
Layer 3 interface to configure.
Enable the interface if necessary. By default, UNIs and
ENIs are disabled and NNIs are enabled.
Enable MD5 authentication in IP EIGRP packets.
Enable authentication of IP EIGRP packets.
Return to global configuration mode.
Identify a key chain and enter key-chain configuration
mode. Match the name configured in Step 4.
In key-chain configuration mode, identify the key
number.
In key-chain key configuration mode, identify the key
string.
(Optional) Specify the time period during which the key
can be received.
The start-time and end-time syntax can be either
hh:mm:ss Month date year or hh:mm:ss date Month
year. The default is forever with the default start-time
and the earliest acceptable date as January 1, 1993. The
default end-time and duration is infinite.
(Optional) Specify the time period during which the key
can be sent.
The start-time and end-time syntax can be either
hh:mm:ss Month date year or hh:mm:ss date Month
year. The default is forever with the default start-time
and the earliest acceptable date as January 1, 1993. The
default end-time and duration is infinite.
Return to privileged EXEC mode.
