Chapter 35 Configuring Layer 3 Interfaces
Configuring EIGRP Stub Routing
To display various routing statistics, use the following commands:
EIGRP Configuration Examples
This section contains the following examples:
• Route Summarization Example
• Route Authentication Example
• Stub Routing Example
Route Summarization Example
The following example disables autosummarization and causes EIGRP to summarize network 10.0.0.0
out Ethernet interface 0 only:
interface Ethernet 0
ip summary-address eigrp 1 10.0.0.0 255.0.0.0
!
router eigrp 1
network 172.16.0.0
no auto-summary
Note You should not use the ip summary-address eigrp summarization command to generate the default
route (0.0.0.0) from an interface because it creates an EIGRP summary default route to the null 0
interface with an administrative distance of 5. The low administrative distance of this default route can
cause this route to displace default routes learned from other neighbors from the routing table. If the
default route learned from the neighbors is displaced by the summary default route, or if the summary
route is the only default route present, all traffic destined for the default route does not leave the router.
Instead, this traffic is sent to the null 0 interface where it is dropped.
The recommended way to send only the default route out a given interface is to use a distribute-list
command. You can configure this command to filter all outbound route advertisements sent out the
interface with the exception of the default (0.0.0.0).
Command Purpose
Switch# show ip eigrp interfaces [interface] [as-number]
Displays information about interfaces configured for
EIGRP.
Switch# show ip eigrp neighbors [type|number|static]
Displays the EIGRP discovered neighbors.
Switch# show ip eigrp topology [autonomous-system-number |
[[ip-address] mask]]
Displays the EIGRP topology table for a given
process.
Switch# show ip eigrp traffic [autonomous-system-number]
Displays the number of packets sent and received for
all or a specified EIGRP process.
