DHCPv6 snooping
DHCPv6 snooping is a feature that provides security by filtering untrusted DHCPv6
messages and by building and maintaining a DHCPv6 snooping binding table. An
untrusted message is a message that is received from outside the network or firewall
and that can cause traffic attacks within your network. The DHCPv6 snooping binding
table contains the MAC address, IP address, lease time, binding type, VLAN number,
and interface information that corresponds to the local untrusted interfaces of a switch.
An untrusted interface is an interface that is configured to receive messages from outside
the network or firewall. A trusted interface is an interface that is configured to receive
only messages from within the network.
DHCPv6 snooping acts like a firewall between untrusted hosts and DHCPv6 servers. It
also provides way to differentiate between untrusted interfaces connected to the end
user and trusted interfaces connected to the DHCPv6 server or another switch.
