Page 307 DHCPv6 server uses T1 and T2 to control the time at which the client contacts with the server to extend the lifetimes on any addresses in the IA_NA before the lifetimes expire. After T1, the client sends the server (S1) (from which the addresses in the IA_NA were obtained) a Renew message. If NBG4615 User’s Guide...
Page 308 Prefix delegation enables an IPv6 router to use the IPv6 prefix (network address) received from the ISP (or a connected uplink router) for its LAN. The NBG4615 uses the received IPv6 prefix (for example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements (RAs) regularly by multicast, the NBG4615 passes the IPv6 prefix information to its LAN hosts.
Page 309 When the NBG4615 needs to send a packet, it first consults the destination cache to determine the next hop. If there is no matching entry in the destination cache, the NBG4615 uses the prefix list to determine whether the destination address is on-link and can be reached directly without passing through a router.
