4.26 DHCPv6 Configuration
DHCPv6 Overview
Dynamic Host Configuration Protocol of IPv6 (DHCPv6) is used by a network host to
dynamically apply for host configuration from a server.
ZXR10 2900E series system supports the following DHCPv6 functions:
1.
DHCPv6 snooping function. DHCPv6 servers and clients do not support authentication
mechanism. DHCPv6 servers created illegally and privately bring confusion to address
allocation, gateway and DNS parameters of some hosts. As a result, these hosts
cannot connect to external networks properly. In addition, there are problems such
as IP spoofing, MAC address spoofing and user ID spoofing from illegal clients, and
DHCPv6 server address exhaustion. On the basis of DHCPv6 snooping, the Option82
technology can solve these security problems effectively.
2.
IP source guard function. By listening to the DHCPv6 interaction procedure between
a client and a server, the system records the IP address allocated to the client by the
server. The system filters out packets with other source IP addresses on ports, thus
preventing spoofing.
Configuring DHCPv6
The DHCPv6 configuration includes the following commands:
Command
Function
zte(cfg)#
set dhcpv6 snooping
{
enable
|
disable
}
Enables or disables the DHCPv6
snooping function globally.
zte(cfg)#
set dhcpv6 snooping
{
add
|
delete
}
port
<
portlist
>
Enables or disables the DHCPv6
snooping function on a port.
zte(cfg)#
set dhcpv6 port
<
1-28
>{
server
|
cascade
|
client
}
Sets the attribute of a port in the
DHCPv6 snooping function.
zte(cfg)#
set dhcpv6 ip-source-guard
{
add
|
delete
}
port
<
portlist
>
Enables or disables the ip-source-guard
function on a port.
