IPv6 Interface

Default Setting
Disabled
Command Mode
Interface Configuration (VLAN)
Command Usage
◆ The “other-stateful-configuration” flag tells hosts that they should use stateful
autoconfiguration to obtain information other than addresses from a DHCPv6
server.
◆ Some hosts interpret the “other stateful configuration” flag to indicate that they
should use stateless address autoconfiguration to get IPv6 address (based on
the IPv6 prefixes found in router advertisements) and stateful
autoconfiguration to get other non-address parameters from DHCPv6 servers.
In this case, the absence of both the “managed address configuration” flag and
the “other stateful configuration” flag is interpreted to mean that they should
use only stateless autoconfiguration to obtain addresses.
Example
The following tells hosts to use stateful autoconfiguration to obtain other non-
address information from a DHCPv6 server:
Console(config)#interface vlan 1
Console(config)#ipv6 nd other-config-flag
Console(config)#
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

Command Usage

router advertisements and by the router itself.
