Chapter 1 Configuring EIGRP
Customizing EIGRP
Configuring the Summary Aggregate Addresses on Interfaces
You can configure a summary addresses on a per-interface basis. You need to manually define summary
addresses if you want to create summary addresses that do not occur at a network number boundary or
if you want to use summary addresses on an ASA with automatic route summarization disabled. If any
more specific routes are in the routing table, EIGRP will advertise the summary address out the interface
with a metric equal to the minimum of all more specific routes.
To create a summary address, perform the following steps:
Detailed Steps
Step 2
hostname(config-router)# 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 fall 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
“Defining a Network for an EIGRP Routing
Process” section on page 1-6 .
Step 3
passive-interface { default | if-name }
Example:
hostname(config)# router eigrp 2
hostname(config-router)# network 10.0.0.0
255.0.0.0
hostname(config-router)# passive-interface
{default}
Prevents an interface from sending or receiving EIGRP routing
message.
Using the default keyword disables EIGRP routing updates on all
interfaces. Specifying an interface name, as defined by the
nameif command, disables EIGRP routing updates on the
specified interface. You can use multiple passive-interface
commands in your EIGRP router configuration.
Command Purpose
Command Purpose
Step 1
interface phy_if
Example:
hostname(config)# interface inside
Enters interface configuration mode for the interface on which
you are changing the delay value used by EIGRP.
Step 2
summary-address eigrp as-num address mask
[ distance ]
Example:
hostname(config-if)# summary-address eigrp
2 address mask [20]
Creates the summary address.
By default, EIGRP summary addresses that you define have an
administrative distance of 5. You can change this value by
specifying the optional
distance argument in the
summary-address command.
