DES-7200 Configuration Guide Chapter 2 IPv6 Configuration
2-14
Prefix: IPv6 address prefix of the local link, which can be used for the on-link
confirmation or the stateless address auto-configuration, including the configuration of
other parameters for the prefix.
Rs-initerval: Interval of sending the neighbor solicitation message.
Reachabletime: Time maintained after considering the neighbor reachable.
We configure the above parameters in the IPv6 interface property.
Caution
1. By default, no Router Advertisement (RA) message is sent
actively on the interface. To do so, you can use the command no ipv6
nd suppress-ra in the interface configuration mode.
2. In order to make the stateless address auto-configuration of the
node work normally, the length of the prefix for the router
advertisement (RA) message should be 64 bits.
2.1.5.5 Redirection
After receiving the IPv6 packets, the router discovers the better next-hop and sends
the ICMP redirection message to notify the host of the better next-hop. Next time the
host sends the IPv6 packets to the better next-hop directly.
2.2 IPv6 Configuration
The following will introduce the configuration of various function modules of the IPv6
respectively:
2.2.1 Configuring IPv6
Address
This section describes how to configure an IPv6 address on an interface. By default,
no IPv6 address is configured.
Caution
Once an interface is created and its link status is UP, the system will
automatically generate the local link address for the interface. At
present, the IPv6 doesn’t support anycast address.
To configure an IPv6 address, execute the following commands in the global
configuration mode:
