Customizing EIGRP

neighbor that receives a packet informing it of the stub status will not query the stub router for any
routes, and a router that has a stub peer will not query that peer. The stub router depends on the
distribution router to send the correct updates to all peers.

To enable the ASA as an EIGRP stub routing process, perform the following steps:

Detailed Steps

Note

A stub routing process does not maintain a full topology table. At a minimum, stub routing needs a
default route to a distribution router, which makes the routing decisions.

Customizing EIGRP

This section describes how to customize the EIGRP routing and includes the following topics:

Defining a Network for an EIGRP Routing Process, page 27-5

Configuring Interfaces for EIGRP, page 27-6

Configuring the Summary Aggregate Addresses on Interfaces, page 27-8

Changing the Interface Delay Value, page 27-9

Command

Purpose

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 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 section

“Configuring Passive Interfaces”

section on page 27-7

.

Step 3

eigrp stub

{receive-only | [connected]

[redistributed] [static] [summary]}

Example:

hostname(config)# router eigrp 2

hostname(config-router)# network 10.0.0.0

255.0.0.0

hostname(config-router)# eigrp stub

{receive-only | [connected]

[redistributed] [static] [summary]}

Configures the stub routing process. You must specify which
networks are advertised by the stub routing process to the
distribution router. Static and connected networks are not
automatically redistributed into the stub routing process.
