Chapter 27 Configuring EIGRP
Customizing EIGRP
Detailed Steps
Defining an EIGRP Neighbor
EIGRP hello packets are sent as multicast packets. If an EIGRP neighbor is located across a non
broadcast network, such as a tunnel, you must manually define that neighbor. When you manually define
an EIGRP neighbor, hello packets are sent to that neighbor as unicast messages.
To manually define an EIGRP neighbor, perform the following steps:
Step 1 router eigrp as-num
Example:
hostname(config)# router eigrp 2
Creates an EIGRP routing process and enters router configuration
mode for this EIGRP process.
The as-num argument is the autonomous system number of the
EIGRP routing process.
Step 2 network ip-addr [mask]
Example:
hostname(config)# router eigrp 2
hostname(config-router)# network 10.0.0.0
255.0.0.0
Configures the interfaces and networks that participate in EIGRP
routing. You can configure one or more network statements with
this command.
Directly connected and static networks that fall within the defined
network are advertised by the ASA. Additionally, only interfaces
with an IP address that falls within the defined network
participate in the EIGRP routing process.
If you have an interface that you do not want to have participate
in EIGRP routing, but that is attached to a network that you want
advertised, see the
“Configuring EIGRP” section on page 27-3 .
Step 3 interface phy_if
Example:
hostname(config)# interface phy_if
Enters interface configuration mode for the interface on which
you are configuring EIGRP message authentication.
Step 4 authentication mode eigrp as-num md5
Example:
hostname(config)# authentication mode
eigrp 2 md5
Enables MD5 authentication of EIGRP packets.
The as-num argument is the autonomous system number of the
EIGRP routing process configured on the ASA. If EIGRP is not
enabled or if you enter the wrong number, the ASA returns the
following error message:
% Asystem(100) specified does not exist
Step 5 authentication key eigrp as-num key key-id
key-id
Example:
hostname(config)# authentication key eigrp
2 cisco key-id 200
Configures the key used by the MD5 algorithm.
The as-num argument is the autonomous system number of the
EIGRP routing process configured on the ASA. If EIGRP is not
enabled or if you enter the wrong number, the ASA returns the
following error message:
% Asystem(100) specified does not exist
The key argument can include up to 16 characters.
The key-id argument is a number that can range from 0 to 255.
