Configure manual summarization eigrp

 · The manual summarization in EIGRP is configured on the per-interface basis. The syntax of the command is: (config-if)ip summary-address eigrp ASN SUMMARY_ADDRESS SUBNET_MASK. Consider the following example: In the example above we have a network of three routers running EIGRP. R1 has two directly connected subnets: . Let’s create a basic EIGRP configuration: R1(config)#router eigrp 1 R1(config-router)#no auto-summary R1(config-router)#network R1(config-router)#network R2(config)#router eigrp 1 R2(config-router)#no auto-summary R2(config-router)#network Just a basic EIGRP configuration. This is what the routing table of R2 looks like.  · To summarize in eigrp, we need to go to the interface connecting to R1 and enter the command below: R2 (config-if)#ip summary-address eigrp 25 If you are not cleared on how we got the summary mask, see here for how to get summary mask for route summarization. The routing table of R1:Estimated Reading Time: 2 mins.

* It supports manual summarization * It is a hybrid protocol. (It has the characteristics of both link state and distance vector protocols) * It supports authentication. Our objective in this lab is to configure eigrp for the network represented in the diagram above. The subnets are configured on the loopbacks on both routers. Enters interface configuration mode. Router(config-if)#ip summary-address eigrp Enables manual summarization for EIGRP autonomous system on this specific interface for the given address and mask. An administrative distance of 75 is assigned to this summary route. When a router running EIGRP is configured for manual summarization, issuing command: ip summary-address eigrp. To configure a summary aggregate address for a specified interface, use the ip summary-address eigrp command in interface configuration mode. To disable a configuration, use the no form of this command.

The ip summary-address eigrp configuration command allows you to configure manual summary addresses on a per-interface basis: Router1# configure terminal. Advanced EIGRP Configurations. Manual Summarization. While automatic summarization is not available for EIGRP IPv6 networks, it is possible to enable manual. Manual Summary: needs to be configured by the administrator depending on the requirement. It is done on major network boundaries and the subnet will be.
