Chapter 9 Configuring IP Routing
Use the following debug commands only to troubleshoot specific problems or during troubleshooting
sessions with Cisco TAC. Debugging output is assigned high priority in the CPU process and can render
the system unusable. It is best to use debug commands during periods of lower network traffic and fewer
users. Debugging during these periods decreases the likelihood that increased debug command
processing overhead will affect system performance.

EIGRP Routing Overview

EIGRP is an enhanced version of IGRP developed by Cisco. Unlike IGRP and RIP, EIGRP does not send
out periodic route updates. EIGRP updates are sent out only when the network topology changes.
Neighbor discovery is the process that the security appliance uses to dynamically learn of other routers
on directly attached networks. EIGRP routers send out multicast hello packets to announce their
presence on the network. When the security appliance receives a hello packet from a new neighbor, it
sends its topology table to the neighbor with an initialization bit set. When the neighbor receives the
topology update with the initialization bit set, the neighbor sends its topology table back to the security
appliance.
