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:
Step 5
ip hello-interval eigrp autonomous-system-number
seconds
(Optional) Change the hello time interval for an EIGRP
routing process. The range is 1 to 65535 seconds. The
default is 60 seconds for low-speed NBMA networks and 5
seconds for all other networks.
Step 6
ip hold-time eigrp autonomous-system-number
seconds
(Optional) Change the hold time interval for an EIGRP
routing process. The range is 1 to 65535 seconds. The
default is 180 seconds for low-speed NBMA networks and
15 seconds for all other networks.
Caution Do not adjust the hold time without consulting
Cisco technical support.
Step 7
no ip split-horizon eigrp autonomous-system-number (Optional) Disable split horizon to allow route information
to be advertised by a router out any interface from which that
information originated.
Step 8
end Return to privileged EXEC mode.
Step 9
show ip eigrp interface Display which interfaces EIGRP is active on and
information about EIGRP relating to those interfaces.
Step 10
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode, and specify the
Layer 3 interface to configure.
Step 3
ip authentication mode eigrp autonomous-system md5 Enable MD5 authentication in IP EIGRP packets.
Step 4
ip authentication key-chain eigrp autonomous-system
key-chain
Enable authentication of IP EIGRP packets.
Step 5
exit Return to global configuration mode.
Step 6
key chain name-of-chain Identify a key chain and enter key-chain configuration
mode. Match the name configured in Step 4.
Step 7
key number In key-chain configuration mode, identify the key
number.
Step 8
key-string text In key-chain key configuration mode, identify the key
string.
