IPv6 Address Auto-Configur
ation
There are two types of IPv6 address auto-configuration:
�
�
Stateful address auto-configuration uses Plug and Play mode. No
Stateful
Address Auto- manual intervention is need to insert a node to network and start
Configuration
up this node.
Stateful address auto-configuration uses two types of mechanisms
to support Plug and Play mode:
�
�
These two mechanisms allow IP node to obtain configuration in-
formation from BOOTP server or DHCP server. BOOTP and DHCP
use stateful auto-configuration, that is, servers should keep and
manage the state information of each node.
All interfaces of each IPv6 node should have their own link-local
Stateless
Address Auto- addresses. A link-local address consists of interface ID and prefix
Configuration
of local link FE80::/10. It is configured on interface automatically.
Nodes on the same link can use link-local address to communicate.
Chapter 3 IPv6 Neighbor Discovery Protocol Configuration
use a pair of NS and NA messages to get link layer address from
the peer, since link layer address of the sender is contained in
NS message.
When NS message is not received, node can also send NA mes-
sage to advertise change of link address.
Redirect Message
Router notifies host that a better next hop to destination ad-
dress is available.
Link-Layer Address Change:
If the node knows that its link-layer address is changed, it can
send some multicast NA messages to notify other local nodes
to update cached link layer addresses.
Ingress Load Balancing:
A node with repeated interfaces hopes to receive traffic on mul-
tiple interfaces of the same link in mode of load balancing. For
example, a network driver can be used as a logical interface,
represents multiple network interfaces and has multiple link
layer addresses. Load balancing allows the router to omit the
source link layer address in RA message and forces neighbor
to use NS message to learn link layer address of the router.
In NA message replied by router, different link layer addresses
are contained according to nodes that send NA messages.
