| IP Configuration
Setting the Switch’s IP Address (IP Version 6)
– 487 –
neighbor. Therefore, avoid using very short intervals for normal IPv6
operations.
When a non-default value is configured, the specified interval is used both for
router advertisements and by the router itself.
◆ ND Reachable-Time – The amount of time that a remote IPv6 node is
considered reachable after some reachability confirmation event has occurred.
(Range: 0-3600000 milliseconds)
Default: 30000 milliseconds is used for neighbor discovery operations,
0 milliseconds is advertised in router advertisements.
■
The time limit configured by this parameter allows the router to detect
unavailable neighbors. During the neighbor discover process, an IPv6 node
will multicast neighbor solicitation messages to search for neighbor nodes.
For a neighbor node to be considered reachable, it must respond to the
neighbor soliciting node with a neighbor advertisement message to
become a confirmed neighbor, after which the reachable timer will be
considered in effect for subsequent unicast IPv6 layer communications.
■
This time limit is included in all router advertisements sent out through an
interface, ensuring that nodes on the same link use the same time value.
■
Setting the time limit to 0 means that the configured time is unspecified by
this router.
◆ Restart DHCPv6 – When DHCPv6 is restarted, the switch may attempt to
acquire an IP address prefix through stateful address autoconfiguration. If the
router advertisements have the “other stateful configuration” flag set, the
switch may also attempt to acquire other non-address configuration
information (such as a default gateway) when DHCPv6 is restarted.
Prior to submitting a client request to a DHCPv6 server, the switch should be
configured with a link-local address using the Address Autoconfig option. The
state of the Managed Address Configuration flag (M flag) and Other Stateful
Configuration flag (O flag) received in Router Advertisement messages will
determine the information this switch should attempt to acquire from the
DHCPv6 server as described below.
■
Both M and O flags are set to 1:
DHCPv6 is used for both address and other configuration settings.
This combination is known as DHCPv6 stateful autoconfiguration, in which
a DHCPv6 server assigns stateful addresses to IPv6 hosts.
■
The M flag is set to 0, and the O flag is set to 1:
DHCPv6 is used only for other configuration settings.
Neighboring routers are configured to advertise non-link-local address
prefixes from which IPv6 hosts derive stateless addresses.
