The UPnP Screen
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
See
page 122
for more information on UPnP.
Use the following screen to enable or disable the UPnP function on your AMG1302/AMG1202-
TSeries. Click
Network Setting > Home Networking
> UPnP
to display the screen shown next.

The IP Alias Screen
IP alias allows you to partition a physical network into different logical networks over the same
Ethernet interface. The AMG1302/AMG1202-TSeries supports multiple logical LAN interfaces via its
physical Ethernet interface with the AMG1302/AMG1202-TSeries itself as the gateway for the LAN
network.

IPv6 LAN Setup
Link Local Address
Type
Select
Manual
to manually enter a link local address. Select
EUI64
to use the EUI-64
format to generate a link local address from the Ethernet MAC address.
IPv6 Address
If you selected
Manual
in the
Link Local Address Type
field, enter the LAN IPv6
address you want to assign to your AMG1302/AMG1202-TSeries in hexadecimal
notation, for example, fe80::1 (factory default).
Prefix
Enter the address prefix to specify how many most significant bits in an IPv6 address
compose the network address.
MLD Snooping
Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the
presence of MLD hosts who wish to receive multicast packets and the IP addresses of
multicast groups the hosts want to join on its network. Select
Enabled
to activate
MLD Snooping on the AMG1302/AMG1202-TSeries. This allows the AMG1302/
AMG1202-TSeries to check MLD packets passing through it and learn the multicast
group membership. It helps reduce multicast traffic.

Lan Global Identifier
Type
Select
Manual
to manually enter a LAN Identifier as the interface ID to identify the
LAN interface. The LAN Identifier is appended to the IPv6 address prefix to create the
routable global IPv6 address. Select
EUI64
to use the EUI-64 format to generate an
interface ID from the Ethernet MAC address.
Lan Identifier
If you selected
Manual
, enter the LAN Identifier in this field. The LAN identifier should
be unique and 64 bits in hexadecimal form. Every 16 bit block should be separated by
a colon as in XXXX:XXXX:XXXX:XXXX where X is a hexadecimal character. Blocks of
zeros can be represented with double colons as in XXXX:XXXX::XXXX.
LAN IPv6 Address Setting
Delegate prefix from
WAN
Select this option to automatically obtain an IPv6 network prefix from the service
provider or an uplink router.
Static
Select this option to configure a fixed IPv6 address for the AMG1302/AMG1202-
TSeries’s LAN IPv6 address.
Static IPv6 Address
Prefix
If you select static IPv6 address, enter the IPv6 address prefix that the AMG1302/
AMG1202-TSeries uses for the LAN IPv6 address.
Prefix length
If you select static IPv6 address, enter the IPv6 prefix length that the AMG1302/
AMG1202-TSeries uses to generate the LAN IPv6 address.
An IPv6 prefix length
specifies how many most significant bits (starting from the left)
in the address compose the network address. This field displays the bit number of the
IPv6 subnet mask.
Preferred Lifetime
Enter the preferred lifetime for the prefix.
Valid Lifetime
Enter the valid lifetime for the prefix.
RADVD Setup
Send RA on
Select this to have the AMG1302/AMG1202-TSeries send router advertisement
messages to the LAN hosts.
Router advertisement is a response to a router solicitation or a periodical multicast
advertisement from a router to advertise its presence and other parameters, such as
IPv6 prefix and DNS information.
Router solicitation is a request from a host to locate a router that can act as the
default router and forward packets.
Note: The LAN hosts neither generate global IPv6 addresses nor communicate with
other networks if you disable this feature.
Delegate M/O flag
from WAN
Select this to have the AMG1302/AMG1202-TSeries obtain the M/O (Managed/Other)
flag setting from the service provider or uplink router.
Manual
Select this to specify the M/O flag setting manually.
Managed config flag
on
Select this to have the AMG1302/AMG1202-TSeries indicate to hosts to obtain network
settings (such as prefix and DNS settings) through DHCPv6.
Clear this to have the AMG1302/AMG1202-TSeries indicate to hosts that DHCPv6 is
not available and they should use the prefix in the router advertisement message.
Other config flag on
Select this to have the AMG1302/AMG1202-TSeries indicate to hosts to obtain DNS
information through DHCPv6.
Clear this to have the AMG1302/AMG1202-TSeries indicate to hosts that DNS
information is not available in this network.
Advertisement
interval option on
Select this to have the Router Advertisement messages the VDSL Router sends specify
the allowed interval between Router Advertisement messages.
Hop limit
Enter the maximum number of network segments that a packet can cross before
reaching the destination. When forwarding an IPv6 packet, IPv6 routers are required
to decrease the Hop Limit by 1 and to discard the IPv6 packet when the Hop Limit is 0.
Possible value for this field are 0-255.

Router Lifetime
Enter the time in seconds that hosts should consider the AMG1302/AMG1202-TSeries
to be the default router. Possible values for this field are 0-9000.
Router Preference
Select the router preference (
Low
,
Medium
or
High
) for the AMG1302/AMG1202-
TSeries. The AMG1302/AMG1202-TSeries sends this preference in the router
advertisements to tell hosts what preference they should use for the AMG1302/
AMG1202-TSeries. This helps hosts to choose their default router especially when
there are multiple IPv6 router in the network.
Note: Make sure the hosts also support router preference to make this function work.
Reachable Time (ms)
Enter the time in milliseconds that can elapse before a neighbor is detected. Possible
values for this field are 0-3600000.
Retrans Timer (ms)
Enter the time in milliseconds between neighbor solicitation packet retransmissions.
Possible values for this field are 1000-4294967295.
RA Interval
Enter the time in seconds between router advertisement messages. Possible values for
this field are 4-1800.
Delegate MTU from
WAN
Select this to have the AMG1302/AMG1202-TSeries obtain the MTU setting from the
service provider or uplink router.
Manual
Select this to specify the MTU manually.
MTU
The Maximum Transmission Unit. Type the maximum size of each IPv6 data packet, in
bytes, that can move through this interface. If a larger packet arrives, the AMG1302/
AMG1202-TSeries divides it into smaller fragments.

servers’ IPv6 address in the fields below.
Primary DNS
This field is available if you choose
Manual
as the DNSv6 mode. Enter the first DNS
server IPv6 address the AMG1302/AMG1202-TSeries passes to the DHCP clients.
