convergence time. Recomputation is processor-intensive; it is advantageous to avoid unneeded
recomputation. When a topology change occurs, DUAL will test for feasible successors. If there are
feasible successors, it will use any it finds in order to avoid unnecessary recomputation.
The protocol-dependent modules are responsible for network layer protocol-specific tasks. An example
is the EIGRP module, which is responsible for sending and receiving EIGRP packets that are
encapsulated in IP. It is also responsible for parsing EIGRP packets and informing DUAL of the new
information received. EIGRP asks DUAL to make routing decisions, but the results are stored in the IP
routing table. Also, EIGRP is responsible for redistributing routes learned by other IP routing protocols.
EIGRP Configuration Task List
To configure EIGRP, perform the tasks described in the following sections. The tasks in the first section
are required; the tasks in the remaining sections are optional:
Enabling EIGRP (Required)
Making the Transition from IGRP to EIGRP (Optional)
Logging EIGRP Neighbor Adjacency Changes (Optional)
Configuring the Percentage of Link Bandwidth Used (Optional)
Adjusting the EIGRP Metric Weights (Optional)
Applying Offsets to Routing Metrics (Optional)
Disabling Route Summarization (Optional)
Configuring Summary Aggregate Addresses (Optional)
Configuring Floating Summary Routes (Optional)
Configuring EIGRP Route Authentication (Optional)
Configuring EIGRP Protocol-Independent Parameters (Optional)
Configuring EIGRP Stub Routing (Optional)
Monitoring and Maintaining EIGRP(Optional)
See the section “EIGRP Configuration Examples” at the end of this chapter for configuration examples.
Enabling EIGRP
To create an EIGRP routing process, use the following commands beginning in global configuration
mode:
EIGRP sends updates to the interfaces in the specified networks. If you do not specify the network of an
interface, the interface will not be advertised in any EIGRP update.
Command Purpose
Step 1
Router(config)# router eigrp autonomous-system
Enables an EIGRP routing process in global
configuration mode.
Step 2
Router(config-router)# network network-number
Associates networks with an EIGRP routing process
in router configuration mode.
