Use this procedure to determine the source of an IPv6 address or set of IPv6 addresses. The discovery prefix also permits other tables to share the information through a pointer rather than by copying. For example, when the node configures both a unicast and anycast address for a prefix, the ipAddressPrefix objects for those addresses point to a single row in the table.
The following table describes the fields of the Discovery Prefix tab.
Variable | Value |
---|---|
IfIndex | Specifies a read-only value indicating the unique value to identify an IPv6 interface. |
Prefix | Configures the prefix to create an IPv6 address in the IPv6 interface table. |
PrefixLen | Configures the mask to create an IPv6 prefix entry as either advertised or suppressed. |
VlanId | Specifies the VLAN ID of the IPv6 interface. |
UseDefaultVal | Select one of the values to set its value to default value. This is a bitmask field, setting all the bits means that all the options will be reverted to default values. |
ValidLife | Configures the valid lifetime in seconds that indicates the length of time this prefix is advertised. The default is 2592000. |
PreferredLife | Configures the preferred lifetime in seconds that indicates the length of time this prefix is advertised. The default value is 604800. |
Infinite | Configures the prefix valid lifetime so it never expires. The default is false. |
OnLinkFlag | Configures the prefix for use when determining if a node is onlink. This value is placed in the L-bit field in the prefix information option. It is a 1-bit flag. The default is true. |
AutoFlag | Configures the prefix for use as the autonomous address configuration. This value is placed in the autoflag field in the prefix information option. It is a 1-bit flag. The default is true. |
AddressEui | Configures the EUI address. Use an EUI-64 interface ID in the low-order 64-bits of the address when the ID is not specified in the address field. If enabled, use EUI, or use EUI-64 and the complement Universal/Local (U/L) bit. This operation provides for both global and link-local addresses. After you create the entry, you cannot modify this value. This value is valid for use only when the PrefixLength is 64 or less. The default is eui-not-used. |
NoAdvertise | Select true to not include the prefix in the neighbor advertisement. The default is false. |
