Advertisement Prefixes for the LAN

You need to configure the prefixes that are advertised in the LAN RAs. For a 6to4 address,

you need to specify only the site level aggregation identifier (SLA ID) and the prefix lifetime.

For a global, local, or ISATAP address, you need to specify the prefix, prefix length, and prefix

lifetime.

 To add an advertisement prefix for the LAN:

1. On

the RADVD screen for the LAN, under the List of Prefixes to Advertise table, click

Add. The Add Advertise Prefixes screen displays:

RA Flags Specify what type of information the DHCPv6 server provides in the LAN by making a

selection from the drop-down list:

• Managed.

• Oth

other configuration information such as DNS information is available through the

DHCPv6 server.

Note: Irrespective of the RA flag settings, the RADVD provides information about the

pre

fix, prefix length, and gateway addresses and is also used for autoconfiguration of

the IP address.
