Advertisement
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.
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.
RA Mode
Interface – Shows port or trunk configuration page.
◆
RA Guard – Blocks incoming Router Advertisement and Router
◆
Redirect packets. (Default: Disabled)
IPv6 Router Advertisements (RA) convey information that enables
nodes to auto-configure on the network. This information may include
the default router address taken from the observed source address of
the RA message, as well as on-link prefix information. However, note
that unintended misconfigurations, or possibly malicious attacks on the
network, may lead to bogus RAs being sent, which in turn can cause
operational problems for hosts on the network.
RA Guard can be used to block RAs and Router Redirect (RR) messages
on the specified interface. Determine which interfaces are connected to
known routers, and enable RA Guard on all other untrusted interfaces.

To configure general IPv6 settings for the switch:
Click IP, IPv6 Configuration.
1.
Select Configure Interface from the Action list.
2.
Select VLAN mode.
3.
Specify the VLAN to configure.
4.
Specify the VLAN to configure, enable IPv6 Explicitly to automatically
5.
configure a link-local address and enable IPv6 on the selected interface.
(To manually configure the link-local address, use the Add IPv6 Address
page.) Set the MTU size, the maximum number of duplicate address
detection messages, the neighbor solicitation message interval, and the
amount of time that a remote IPv6 node is considered reachable.
