The ip summary-address eigrp configuration command allows you to configure manual summary addresses on a per-interface basis:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#interface Serial0/0.2
Router1(config-subif)#ip summary-address eigrp 55 172.25.0.0 255.255.0.0
Router1(config-subif)#exit
Router1(config)#end
Router1#
EIGRP can automatically summarize subnet routes into classful network-level routes. You can enable this command with the auto-summary command or disable it with the no auto-summary configuration command:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#router eigrp 55
Router1(config-router)#no auto-summary
Router1(config-router)#exit
Router1(config)#end
Router1#
A useful new feature allows you to configure a leak-map so that the router will advertise the summary route, as well as some subset of the summarized addresses:
Router9# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router9(config)#ip prefix-list 10.5.5/24 permit 10.5.5.0/24
Router9(config)#route-map LEAK10-5-5 permit 10
Router9(config-route-map)#match ip address prefix-list 10.5.5/24
Router9(config-route-map)#exit
Router9(config)#interface Serial0/0
Router9(config-if)#ip summary-address eigrp 55 10.5.0.0 255.255.0.0 leak-map LEAK10-5-5
Router9(config-if)#exit
Router9(config)#end
Router9#
Summarization is one of the most powerful features of EIGRP, and one of the most frequently overlooked methods for improving network efficiency. Unlike RIP, which summarizes along classful network boundaries, EIGRP uses CIDR, allowing you to summarize at any bit in the address, as well as allowing supernets. Conversely, EIGRP allows you to summarize at any router in the network. This means that with EIGRP, you can have multiple hierarchical levels of address summarization, which can greatly improve the maximum size and efficiency of a large network, but only if it is designed properly to allow it.
The auto-summary command was enabled by default until IOS version 12.2(8)T, when it started to be disabled by default.

You can see all of the summarization information, including which interfaces will send out summary addresses, using the show ip protocols command:
Router1#show ip protocols
Routing Protocol is "eigrp 55"
Outgoing update filter list for all interfaces is not set
Redistributed static filtered by 7
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
Redistributing: static, eigrp 55
Automatic network summarization is not in effect
Address Summarization:
172.25.0.0/16 for Serial0/0.2
Summarizing with metric 28160
Maximum path: 4
Routing for Networks:
10.0.0.0
172.22.0.0
172.25.0.0
Routing Information Sources:
Gateway Distance Last Update
10.1.1.1 90 1d23h
172.25.1.7 90 00:00:57
172.25.2.2 90 00:00:57
172.22.1.4 90 00:00:57
Distance: internal 90 external 170
Router1#
In this example, we have only summarized 172.25.0.0/16 on interface Serial0/0.2. However, it is important to remember that you can summarize several networks at the same time on a single interface by simply configuring all of the different summary addresses, as follows:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#interface Serial0/0.2
Router1(config-subif)#ip summary-address eigrp 55 172.25.0.0 255.255.0.0
Router1(config-subif)#ip summary-address eigrp 55 10.0.0.0 255.0.0.0 80
Router1(config-subif)#end
Router1#
When it summarizes addresses, EIGRP will automatically suppress all of the routes that are included in the summary. Of course, if there are no routes to summarize, the router won't distribute the summary address.
The metric of this summary route will be equal to the best metric of the routes being summarized. It is important to remember this because if the route with the best metric goes away for any reason, EIGRP will change the metric of the summary. So if the route with the best metric is unstable, it will make the summary route unstable. If you want to ensure that this doesn't happen, you can configure a static route within the summarized range, and point it to a null interface. Then you must configure the router to redistribute this static route into EIGRP.
The following example shows a CIDR supernet summarization:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#interface Serial0/0.2
Router1(config-subif)#ip summary-address eigrp 55 0.0.0.0 0.0.0.0
Router1(config-subif)#end
Router1#
In this case, if there are any routes to distribute at all, EIGRP will distribute only the default route 0.0.0.0/0 and suppress all of the individual routes. This is actually an extremely useful technique on low-speed WAN links, particularly when this link represents the only path to the rest of the network. In such cases, the remote site only needs to know that it can get to everything it needs through this link. Further, because routing is always done by taking the longest match first, if the remote site happens to have more specific routing information for a particular destination, it won't use this summary route.
Router2#show ip route eigrp
D* 0.0.0.0/0 [90/2172416] via 172.25.2.1, 00:00:30, Serial0.1
Router2#
Leak-maps became available in IOS level 12.3(14)T. This feature allows you to configure a summary address, and also advertise some of the summarized networks. In the example shown in the Solutions section above, we have summarized all of the 10.5.0.0/16 range of addresses:
Router9(config)#interface Serial0/0
Router9(config-if)#ip summary-address eigrp 55 10.5.0.0 255.255.0.0 leak-map LEAK10-5-5
This summary includes a leak-map called LEAK10-5-5, which is defined by using a route map:
Router9(config)#ip prefix-list 10.5.5/24 permit 10.5.5.0/24
Router9(config)#route-map LEAK10-5-5 permit 10
Router9(config-route-map)#match ip address prefix-list 10.5.5/24
This route map does nothing but match a particular prefix, 10.5.5.0/24, and exclude it from summarization. We can then look at the routing table on a neighboring router:
Router2#show ip route 10.0.0.0
Routing entry for 10.0.0.0/8, 9 known subnets
Variably subnetted with 3 masks
Redistributing via eigrp 55

D 10.1.2.1/32 [90/2300416] via 172.20.10.9, 00:20:34, Serial0/0
D 10.5.5.0/24 [90/2838016] via 172.20.10.9, 00:00:37, Serial0/0
D 10.1.1.0/24 [90/2300416] via 172.20.10.9, 00:20:34, Serial0/0
D 10.5.0.0/16 [90/2838016] via 172.20.10.9, 00:18:53, Serial0/0
Router2#
This router now receives both the summary address, 10.5.0.0/16, and the specific prefix 10.5.5.0/24. This can be quite useful in situations when you have imperfect summarization. That is, you might be able to reduce all of the routes for a particular part of your network to a single summary route, 10.5.0.0/17. But if the single network 10.5.5.0/24 resides in a different part of the network, you need to make sure that this specific prefix also appears in routing tables throughout the network. Recall that routers will always use the most specific route when forwarding packets. CCIE RS Training

Previously, if you couldn't summarize all of the prefixes in a network, you had to advertise all of the individual routes. So the leak-map feature allows you to reduce the size of your routing table without causing problems for a few exceptions. CCIE Voice Training

Note that because the feature uses route maps to define the leaked routes, you could also match parameters such as the route type (internal, external, or local) tag, or the router's next-hop interface for that route. For example you could use the interface matching to leak individual routes only if the remote site is on dial backup. CCIE Security Training

Route maps give you much better control over how RIP redistributes external routes. This example uses static routes, but the same principles apply when redistributing routes from other protocols:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#ip route 192.168.10.0 255.255.255.0 172.22.1.4
Router1(config)#ip route 192.168.11.0 255.255.255.0 172.22.1.4
Router1(config)#ip route 192.168.12.0 255.255.255.0 172.22.1.4
Router1(config)#access-list 20 permit 192.168.10.0
Router1(config)#access-list 21 permit 192.168.11.0
Router1(config)#route-map STATIC permit 10
Router1(config-route-map)#match ip address 20
Router1(config-route-map)#set metric 2
Router1(config-route-map)#set tag 2
Router1(config-route-map)#exit
Router1(config)#route-map STATIC permit 20
Router1(config-route-map)#match ip address 21
Router1(config-route-map)#set metric 8
Router1(config-route-map)#route-map STATIC deny 30
Router1(config-route-map)#exit
Router1(config)#router rip
Router1(config-router)#redistribute static route-map STATIC
Router1(config-router)#exit
Router1(config)#end
Router1#
In this example, we want RIP to distinguish among the different routes. There are two parameters that we can change, the metric and the route tag. We have already discussed metrics, which basically represent the distance or cost of the path to the remote network. A route tag is simply an arbitrary number that RIP will attach to a particular route.
The route map in this recipe has three clauses. The first assigns a metric of 2 and a tag of 2 to the network 192.168.10.0. Then it gives a metric of 8 to 192.168.11.0. The last clause discards all other routes.
This kind of redistribution is useful when you want to control how traffic load is balanced between two links. For example, if you have two routers that both connect to the same set of remote networks, you could balance them so that one router has a better metric for half of the routes, and the other has a better metric for the rest of the routes. In this way, you can ensure that both links are used equally, and if one router fails, the other will take over for it.
It is often easier to understand route-maps by looking at the show route-map command rather than the configuration commands. In this case, for example, you can see exactly what access lists apply to each clause, along with all of the values that are set as a result. This output also shows how many times each policy has been applied:
Router1#show route-map STATIC
route-map STATIC, permit, sequence 10
Match clauses:
ip address (access-lists): 20
Set clauses:
metric 2
tag 2
Policy routing matches: 0 packets, 0 bytes
route-map STATIC, permit, sequence 20
Match clauses:
ip address (access-lists): 21
Set clauses:
metric 8
Policy routing matches: 0 packets, 0 bytes
route-map STATIC, deny, sequence 30
Match clauses:
Set clauses:
Policy routing matches: 0 packets, 0 bytes
Router1#
Looking at the RIP database, you can see the metrics that RIP uses for distributing each of these static routes:
Router1#show ip rip database
192.168.10.0/24 auto-summary
192.168.10.0/24 redistributed
[2] via 0.0.0.0,
192.168.11.0/24 auto-summary
192.168.11.0/24 redistributed
[8] via 0.0.0.0,
Router1#
You can also use the route map technique for distributing routes from dynamic routing protocols. For example, if you had another route map called EIGRPMAP that you wanted to use when redistributing routes learned through EIGRP process number 65530, you could configure the router like this:
Router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#router eigrp 65530
Router1(config-router)#network 192.168.1.0
Router1(config-router)#exit
Router1(config)#router rip
Router1(config-router)#redistribute eigrp 65530 route-map EIGRPMAP
Router1(config-router)#end
Router1#

The static routes that we discussed in the previous section all had relatively low administrative distance values. If the router has two routes to the same destination but with different distances, it will always choose the one with the lower distance value. This concept also includes the routes that come from other sources, such as dynamic routing protocols.

Every routing protocol has an administrative distance that indicates how much the router trusts the information it receives by this method. Table 5-3 shows the default values for these administrative distances.

A floating static route is simply one that has an administrative distance value greater than that of the dynamic routing protocol being used. For example, any route that is learned via OSPF will have an administrative distance value is 110 by default. This administrative distance applies to all routes learned by this method regardless of what metric they may have within that protocol.

In the case of static routes, you can directly set the administrative distance for any given static route when you define the route. If the static route's distance value is greater than 110, then any OSPF route that includes this destination is considered better. If OSPF has a route for this destination, the router will use it.

The router will install the floating static route if it doesn't have a similar route from the dynamic routing protocol. Bear in mind, though, that the router will always use the route that has the most precise (longest netmask) match. For example, if the router has learned a route for 10.35.15.0/24 from OSPF, and also has a static route for 10.35.15.0/27, it will use the static route even if it has a higher administrative distance. The administrative distance is used only to decide between competing routes of the same mask length.

Floating static routes are often used to trigger automated backup mechanisms when the routing protocol fails. In this case, you could configure a floating static default route, 0.0.0.0/0, which would point to the dialer interface:

Router(config)#ip route 0.0.0.0 0.0.0.0 Dialer1 190

If the router loses contact with the rest of the network because of a circuit failure, then all of the dynamic routes will drop out of the routing table. The router will then install the floating static route, which will trigger the dial backup connection.
