Chapter 31 | IP Interface Commands
IPv6 Interface
– 930 –
Command Usage
Hosts obtain addresses through either stateful or stateless autoconfiguration.
When the flag is set, they will use stateful autoconfiguration. When the flag is unset
(using the no form of the command), attached hosts will use stateless
autoconfiguration.
Example
The following example enabled the setting of the managed address configuration
flag in IPv6 router advertisements.
Console(config-if)#ipv6 nd managed-config-flag
Console(config-if)#
ipv6 nd ns-interval This command configures the interval between transmitting IPv6 neighbor
solicitation messages on an interface. Use the no form to restore the default value.
Syntax
ipv6 nd ns-interval milliseconds
no ipv6 nd ns-interval
milliseconds - The interval between transmitting IPv6 neighbor solicitation
messages. (Range: 1000-3600000)
Default Setting
1000 milliseconds is used for neighbor discovery operations
0 milliseconds is advertised in router advertisements
Command Mode
Interface Configuration (VLAN)
Command Usage
◆ When a non-default value is configured, the specified interval is used both for
router advertisements and by the router itself.
◆ This command specifies the interval between transmitting neighbor
solicitation messages when resolving an address, or when probing the
reachability of a neighbor. Therefore, avoid using very short intervals for normal
IPv6 operations.
◆ Setting the neighbor solicitation interval to 0 means that the configured time is
unspecified by this router.
Example
The following sets the interval between sending neighbor solicitation messages to
30000 milliseconds:
