Chapter 38 Configuring IP Unicast Routing
Configuring EIGRP
Table 38-7 lists some of the privileged EXEC commands for displaying statistics. For more show ip ospf
database privileged EXEC command options and for explanations of fields in the resulting display, see
the Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols, Release 12.2.
Configuring EIGRP
This section applies only to the Catalyst Switch Module 3110.
Note If the switch is running the IP base image, you can configure complete EIGRP routing. However, the
configuration is not implemented because the IP base image supports only EIGRP stub routing.
After you have entered the eigrp stub router configuration command, only the eigrp stub connected
summary command takes effect. Although the CLI help might show the receive-only and static
keywords, and you can enter these keywords, the switch running the IP base image always behaves as if
the connected and summary keywords were configured.
Enhanced IGRP (EIGRP) is a Cisco-proprietary enhanced version of the IGRP. EIGRP uses the same
distance vector algorithm and distance information as IGRP; however, the convergence properties and
the operating efficiency of EIGRP are significantly improved.
The convergence technology employs an algorithm referred to as the diffusing update algorithm
(DUAL), which guarantees loop-free operation at every instant throughout a route computation. All
devices involved in a topology change can synchronize at the same time. Routers that are not affected by
topology changes are not involved in recomputations.
