Configuring EIGRP
Monitoring OSPF
You can display specific statistics such as the contents of IP routing tables, caches, and databases.
Table 39-6
lists some of the privileged EXEC commands for displaying statistics. For more

Configuring EIGRP
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.
