Figure 10 Secondary Interface Autoconfiguration From an IPv6 Router
1. Primary interface comes up with the link-local address autoconfigured.
2. Host multicasts Router Solicitation.
3. IPv6 Router sends Router Advertisement to host.
4. Host autoconfigures secondary interface (lan0:1) by prepending prefix
(2001:db8:0:13::/64) sent by router to interface identifier (
a00:9ff:fe78:f339). Refer to RFC 2461 “Neighbor Discovery for IP Version 6
(IPv6)” for details.
Manual Configuration and Router Advertisements
Note that even if a primary interface is manually configured, if the host receives prefixes
from router advertisements, then secondary interfaces are autoconfigured. In this case,
the addresses on the secondary interfaces are derived from the interface ID portion of
the manually specified primary interface address.
Manual Configuration Overwriting Autoconfiguration
Manual configuration can overwrite autoconfiguration. When a secondary interface is
configured with a manually assigned address, and if the user chooses an interface index
number that has been used for an already autoconfigured secondary interface, the
manual configuration overwrites the autoconfiguration. When this happens, network
