Dear colleague. The address configuration methods in IPv6 are normally divided into two. One is a stateless auto-configuration (RFC 2462) and other thing is a stateful auto-configuration (RFC 3315). Well, actually, the stateless auto-configuration is done by router advertisement message sent from a router and the statefult auto-configuration is done by DHCPv6 server that nodes obtain the address configuration information with DHCP procedures.
Your question must be about the stateless auto-configuration. A router in the network would have its IPv6 address (network prefix + other) and then the router periodically sends router advertisement message to all node in the network. The router advertisement message includes the prefix information and the address configuration information. In the case that the router only has a link-local adress, the router advertisement message would be wrong because the link-local address cannot be sent as the prefix information in the router advertisement message. Also, even though you only set a prefix information into a router in the network, the router will make a global address if there is another router sending router advertisement message. Cheers.

Dear all, Thankyou for detailed replies regarding my previous question about the need to perform DAD. Another question is regarding the auto-configuration of Routers in an IPv6 network. >From RFC 2462 and also i read somewhere that "With the exception of link-local addresses, address auto-configuration is only specified for HOSTS (and by implication not for routers). Routers must obtain address configuration parameters through another means (for example, manual configuration)". Because every router interface (except loopback ofcourse) should have a global-scope IPv6 address which the MN will use as destination address in BU during Home registration process in MIPv6, so if I manually provide ONLY prefixes to an IPv6 router, then can't the router perform auto-configuration to form a global-scope address from this manually assigned prefix(es)? Clarification would be appreciated. Zarrar _________________________________________________________________ Don't get caught with egg on your face.
