Chapter 1 Configuring IPv6 Neighbor Discovery
Licensing Requirements for IPv6 Neighbor Discovery
Static IPv6 Neighbors
You can manually define a neighbor in the IPv6 neighbor cache. If an entry for the specified IPv6 address
already exists in the neighbor discovery cache—learned through the IPv6 neighbor discovery
process—the entry is automatically converted to a static entry. Static entries in the IPv6 neighbor
discovery cache are not modified by the neighbor discovery process.
Licensing Requirements for IPv6 Neighbor Discovery
The following table shows the licensing requirements for this feature:
Prerequisites for IPv6 Neighbor Discovery
Configure IPv6 addressing according to the
“Configuring IPv6 Addressing” section on page 1-12
Guidelines and Limitations
This section includes the guidelines and limitations for this feature.
Context Mode Guidelines
Supported in single and multiple context mode.
Firewall Mode Guidelines
Supported in routed mode only. Transparent mode is not supported.
Additional Guidelines and Limitations
•
The interval value is included in all IPv6 router advertisements that are sent out of this interface.
•
The configured time enables detecting unavailable neighbors. Shorter configured times enable
detecting unavailable neighbors more quickly; however, shorter times consume more IPv6 network
bandwidth and processing resources in all IPv6 network devices. Very short configured times are not
recommended in normal IPv6 operation.
•
The interval between transmissions should be less than or equal to the IPv6 router advertisement
lifetime if the ASA is configured as a default router by using the
ipv6 nd ra-lifetime
command. To
prevent synchronization with other IPv6 nodes, randomly adjust the actual value used to within 20
percent of the specified value.
•
The
ipv6 nd prefix
command allows control over the individual parameters per prefix, including
whether or not the prefix should be advertised.

License Requirement
All models
Base License.
