5.28 DHCPv6 Configuration

DHCPv6 Overview
The Dynamic Host Configuration Protocol of IPv6 (DHCPv6) is used by a network host to
dynamically request host configuration from a server.
The ZXR10 5250 series system supports the following DHCPv6 functions:
l
DHCPv6 snooping function:
authentication mechanism. Illegally and privately created DHCPv6 servers 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.
l
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
