• Prefix Length—The length of the IPv6 prefix. A decimal value that indicates how
many of the high-order contiguous bits of the address comprise the prefix (the network
portion of the address). A slash mark must precede the decimal value
• Prefix Advertisement—Select to advertise this prefix.
• Valid Lifetime—Remaining length of time, in seconds, that this prefix will continue to
be valid, i.e., time until invalidation. The address generated from an invalidated prefix
should not appear as the destination or source address of a packet.
- Infinite—Select this value to set the field to 4,294,967,295, which represents
infinity.
- User Defined—Enter a value.
• Preferred Lifetime—The remaining length of time, in seconds, that this prefix will
continue to be preferred. After this time has passed, the prefix should no longer be used
as a source address in new communications, but packets received on such an interface
are processed as expected. The preferred-lifetime must not be larger than the valid-
lifetime.
- Infinite—Select this value to set the field to 4,294,967,295, which represents
infinity.
- User Defined—Enter a value.
• Auto Configuration—Enable automatic configuration of IPv6 addresses using
stateless auto configuration on an interface and enable IPv6 processing on the interface.
Addresses are configured depending on the prefixes received in Router Advertisement
messages
• Prefix Status—Select one of the following options:
- Onlink—Configures the specified prefix as on-link. Nodes sending traffic to
addresses that contain the specified prefix consider the destination to be locally
reachable on the link. An onlink prefix is inserted into the routing table as a
connected prefix (L-bit set).
- No-Onlink—Configures the specified prefix as not onlink. A no onlink prefix is
inserted into the routing table as a connected prefix but advertised with a L-bit clear.
- Offlink—Configures the specified prefix as offlink. The prefix will be advertised
with the L-bit clear. The prefix will not be inserted into the routing table as a
connected prefix. If the prefix is already present in the routing table as a connected
prefix (for example, because the prefix was also configured by adding an IPv6
address), it will be removed.
