Configuring EIGRP
Defining an EIGRP Neighbor
EIGRP hello packets are sent as multicast packets. If an EIGRP neighbor is located across a
nonbroadcast 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:
Enter router configuration mode for the EIGRP routing process by entering the following command:
Step 1
hostname(config)# router eigrp as-num
The as-num argument is the autonomous system number of the EIGRP routing process.
Define the static neighbor by entering the following command:
Step 2
hostname(config-router)# neighbor ip-addr interface if_name
The ip-addr argument is the IP address of the neighbor. The if-name argument is the name of the
interface, as specified by the nameif command, through which that neighbor is available. You can define
multiple neighbors for an EIGRP routing process.
Redistributing Routes Into EIGRP
You can redistribute routes discovered by OSPF into the EIGRP routing process. You can also
redistribute static and connected routes into the EIGRP routing process. You do not need to redistribute
static or connected routes if they fall within the range of a network statement in the EIGRP
configuration.
To redistribute routes into the EIGRP routing process, perform the following steps:
(Optional) Create a route-map to further define which routes from the specified routing protocol are
Step 1
redistributed in to the RIP routing process. See the
information about creating a route map.
Step 2
Enter router configuration mode for the EIGRP routing process:
hostname(config)# router eigrp as-num
(Optional) Specify the default metrics that should be applied to routes redistributed into the EIGRP
Step 3
routing process by entering the following command:
hostname(config-router)# default-metric bandwidth delay reliability loading mtu
If you do not specify a default-metric in the EIGRP router configuration, you must specify the metric
values in each redistribute command. If you specify the EIGRP metrics in the redistribute command
and have the default-metric command in the EIGRP router configuration, the metrics in the
redistribute command are used.
Choose one of the following options to redistribute the selected route type into the EIGRP routing

process.

To redistribute connected routes into the EIGRP routing process, enter the following command:
hostname(config-router): redistribute connected [metric bandwidth delay reliability
loading mtu] [route-map map_name]
