Chapter 64 Configuring Routing Policies
EIGRP Routing on Cisco IOS Routers
Step 4 Enter the name of the interface or interface role to define, or click Select to select an interface role from
a list or to create a new one. For more information, see Specifying Interfaces During Policy Definition,
page 6-70.
Step 5 (Optional) In the Hello Interval field, modify the default interval between hello packets sent over the
selected interfaces.
The default is 5 seconds for all interfaces, except for low-speed (T1 or less) NBMA media, for which
the default interval is 60 seconds.
Step 6 (Optional) Deselect the Split Horizon check box to disable the split horizon feature. If you disable this
feature, the selected interfaces can advertise a route out of the interface from which they learned the
route.
Note In general, we recommend that you not disable split horizon unless you are certain that your
application requires the change to properly advertise routes. If you disable split horizon on a
serial interface, and that interface is attached to a packet-switched network, you must disable
split horizon for all routers and access servers in all relevant multicast groups on that network.
Step 7 Click OK to save your definitions locally on the client and close the dialog box. The interface definition
appears in the table on the EIGRP Interfaces tab.
Redistributing Routes into EIGRP
Redistribution refers to using a routing protocol, such as EIGRP, to advertise routes that are learned by
some other means, such as a different routing protocol, static routes, or directly connected routes. For
example, you can redistribute routes from the RIP routing protocol into your EIGRP autonomous system
(AS). Redistribution is necessary in networks that operate in multiple-protocol environments and can be
applied to all IP-based routing protocols.
Before You Begin
• Define at least one EIGRP autonomous system. See Defining EIGRP Routes, page 64-9.

Step 1 Do one of the following:
• (Device view) Select Platform > Routing > EIGRP from the Policy selector, then click the
Redistribution tab in the work area.
• (Policy view) Select Router Platform > Routing > EIGRP from the Policy Type selector. Select
an existing policy or create a new one, and then click the Redistribution tab.
The EIGRP Redistribution tab is displayed. See Table 64-9 on page 64-17 for a description of the fields
on this tab.
