Configuring a Summary Address for EIGRP
You can configure a summary aggregate address for a specified interface. 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. See the “Route Summarization” section on page 4-6.
To configure a summary aggregate address, use the following command in interface configuration mode:
This example causes EIGRP to summarize network 192.0.2.0 out Ethernet 1/2 only:
switch(config)# interface ethernet 1/2
switch(config-if)# no switchport
switch(config-if)# ip summary-address eigrp Test1 192.0.2.0 255.255.255.0
Redistributing Routes into EIGRP
You can redistribute routes in EIGRP from other routing protocols.
BEFORE YOU BEGIN
Ensure that you have enabled the EIGRP feature (see the “Enabling the EIGRP Feature” section on
page 4-9).
You must configure the metric (either through the default-metric configuration option or through a route
map) for routes redistributed from any other protocol.
You must create a route map to control the types of routes that are redistributed into EIGRP. See
Chapter 13, “Configuring Route Policy Manager.”
SUMMARY STEPS
1. configure terminal
Command Purpose
switch(config-if)# ip summary-address
eigrp instance-tag ip-prefix/length
[distance | leak-map map-name]
Example:
switch(config-if)# ip summary-address
eigrp Test1 192.0.2.0/8
Configures a summary aggregate address as either
an IP address and network mask, or an IP
prefix/length. The instance tag and map name can
be any case-sensitive, alphanumeric string up to 20
characters.
You can optionally configure the administrative
distance for this aggregate address. The default
administrative distance is 5 for aggregate
addresses.
