Configuring EIGRP Chapter 8 Configuring IP Routing and DHCP Services hostname(config)# rip inside passive version 2 authentication md5 scorpius 1 If you want to enable passive RIP on all interfaces, but only enable default routes on the inside interface, enter the following commands: hostname(config)# rip inside default version 2 authentication md5 scorpius 1 hostname(config)# rip inside passive version 2 authentication md5 scorpius 1 hostname(config)# rip outside passive version 2 authentication md5 scorpius 1 Note Before testing your configuration, flush the ARP caches on any routers connected to the FWSM. For Cisco routers, use the clear arp command to flush the ARP cache. You cannot enable RIP if OSPF is enabled.

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 FWSM 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 FWSM 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 FWSM. 8-22 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
