page to enter the settings for an
advertisement prefix.
To open this page:
From the

page,

or select an entry and then click

.
STEP 1
Choose an
IPv6 Prefix Type
. Choose the format for the prefix that precedes the
32-bit IPv4 address.
•
6to4
—Choose this option to advertise a 6to4 prefix. Generally, 6to4
tunneling is used for inter-site communication.
If you chose
6to4
as the prefix type, enter the
SLA ID
. The Site-Level
Aggregation Identifier is the interface ID of the interface on which the
advertisements are sent. The default value is 1.
•
Global/Local/ISATAP
—Choose this option to advertise a global, local, or
ISATAP prefix. IPv6 global addresses are globally routable, similar to IPv4
public addresses. Your ISP will typically provide you a block of globally
routable IPv6 addresses that you could configure for stateless
autoconfiguration. Local IPv6 addresses are similar to your IPv4 LAN
addresses which are not globally routable.
If you choose
Global/Local/ISATAP
as the prefix type, enter the following
settings:
-
IPv6 Prefix—
The IPv6 prefix specifies the IPv6 network address.
-
IPv6 Prefix Length—
The prefix length variable is a decimal value that
indicates the number of contiguous, higher-order bits of the address that
make up the network portion of the address.
STEP 2
Enter the
Prefix Lifetime
, which is the number of seconds that the requesting
router is allowed to use the prefix.
