STEP 4 In the DHCPv6 field, choose to disable or enable the DHCPv6 server. If enabled,
the Cisco RV 120W assigns an IP address within the specified range plus
additional specified information to any LAN endpoint that requests DHCP-served
addresses.
STEP 5 Choose the DHCP mode. If stateless is selected, an external IPv6 DHCP server is
not required as the IPv6 LAN hosts are auto-configured by the Cisco RV 120W. In
this case, the router advertisement daemon (RADVD) must be configured on this
device and ICMPv6 router discovery messages are used by the host for auto-
configuration. There are no managed addresses to serve the LAN nodes.
If stateful is selected, the IPv6 LAN host will rely on an external DHCPv6 server to
provide required configuration settings.
STEP 6 (Optional) Enter the domain name of the DHCPv6 server.
STEP 7 Enter the server preference. This field is used to indicate the preference level of
this DHCP server. DHCP advertise messages with the highest server preference
value to a LAN host are preferred over other DHCP server advertise messages.
The default is 255.
STEP 8 Choose the DNS proxy behavior:
• Use DNS Proxy—Check this box to enable DNS proxy on this LAN, or
uncheck this box to disable this proxy. When this feature is enabled, the
router acts as a proxy for all DNS requests and communicate with the ISP’s
DNS servers (as configured in the WAN settings page).
• Use DNS from ISP—This option allows the ISP to define the DNS servers
(primary/secondary) for the LAN DHCP client.
• Use below—If selected, the primary/secondary DNS servers configured
are used. If you chose this option, enter the IP address of the primary and
secondary DNS servers.
STEP 9 Enter the lease/rebind time. Enter the duration (in seconds) for which IP addresses
will be leased to endpoints on the LAN.
STEP 10 Click Save.
Configuring IPv6 Address Pools
This feature allows you to define the IPv6 delegation prefix for a range of IP
addresses to be served by the Cisco RV 120W’s DHCPv6 server. Using a
delegation prefix, you can automate the process of informing other networking
equipment on the LAN of DHCP information specific for the assigned prefix.
