Default router information (whether the device sending the advertisement should be used as a default router and, if so, the amount of time, in seconds, the device should be used as a default router). Additional information for hosts, such as the hop limit and maximum transmission unit (MTU) a host should use in packets that it originates. RAs are also sent in response to device solicitation messages. Device solicitation messages, which have a value of 133 in the Type field of the ICMP packet header, are sent by hosts at system startup or anytime needed so that the host can immediately autoconfigure without needing to wait for the next scheduled RA message. Hosts discover and select default devices by listening to Router Advertisements (RAs). Stateless address autoconfiguration means that the node automatically configures an IPv6 address and other information for its interface according to the address prefix and other configuration parameters in the received RA messages. 3. IPv6 Neighbor Redirect Message A value of 137 in the type field of the ICMP packet header identifies an IPv6 neighbor redirect message. Devices send neighbor redirect messages to inform hosts of better first-hop nodes on the path to a destination. A device will send an IPv6 ICMP redirect message when the following conditions are satisfied: The receiving interface is the forwarding interface. The selected route itself is not created or modified by an IPv6 ICMP redirect message. The selected route is not the default route. The forwarded IPv6 packet does not contain any routing header. You can configure the system's Layer 3 interfaces on this page. Choose the menu Routing→Interface→Interface Config to load the following page. Figure 10-3 Interface Config 185
