Configuring IPv6 Neighbor Discovery
See Chapter 1, "Configuring IPv6 Neighbor Discovery,"
Completing Interface Configuration in Routed Mode
Purpose
Enables stateless autoconfiguration on the interface. Enabling
stateless autoconfiguration on the interface configures IPv6
addresses based on prefixes received in Router Advertisement
messages. A link-local address, based on the Modified EUI-64
interface ID, is automatically generated for the interface when
stateless autoconfiguration is enabled.
Note
Although RFC 4862 specifies that hosts configured for
stateless autoconfiguration do not send Router
Advertisement messages, the ASA does send Router
Advertisement messages in this case. See the ipv6 nd
suppress-ra command to suppress messages.
Assigns a global address to the interface. When you assign a
global address, the link-local address is automatically created for
the interface.
standby specifies the interface address used by the secondary unit
or failover group in a failover pair.
See the "IPv6 Addresses" section on page 1-5
information about IPv6 addressing.
Assigns a global address to the interface by combining the
specified prefix with an interface ID generated from the interface
MAC address using the Modified EUI-64 format. When you
assign a global address, the link-local address is automatically
created for the interface.
You do not need to specify the standby address; the interface ID
will be generated automatically.
See the "IPv6 Addresses" section on page 1-5
information about IPv6 addressing.
Enforces the use of Modified EUI-64 format interface identifiers
in IPv6 addresses on a local link.
The if_name argument is the name of the interface, as specified by
the nameif command, on which you are enabling the address
format enforcement.
See the "Modified EUI-64 Interface IDs" section on page 1-13
