Dynamic Route: Select this option to specify the RIP (Routing Information protocol) version
for WAN interface, including RIP1, RIP2-B and RIP2-M. RIP2-B and RIP2-M are both sent in
RIP2 format, the difference is that RIP2-M using Multicast, while RIP2-B using Broadcast
format.
Direction: Select this option to specify the RIP direction. None is for disabling the RIP
function. Both means the ADSL modem router will periodically send routing information
and accept routing information, and then incorporate them into routing table. IN only
means the ADSL modem router will only accept but will not send RIP packet. OUT only
means the ADSL modem router will only send but will not accept RIP packet.
Multicast: Select IGMP version, or disable the function. IGMP (Internet Group Multicast
Protocol) is a session-layer protocol used to establish membership in a multicast group. The
ADSL ATU-R supports both IGMP version 1 (IGMP v1) and IGMP v2. Select “Disabled” to
disable it.
2) Static IP Address
Select this option if your ISP provides static IP information to you. You should set static IP
address, IP subnet mask, and gateway address in the screen below (shown in Figure 4-8).

Note:
Each IP address entered in the fields must be in the appropriate IP form, which is four IP octets
separated by a dot (x.x.x.x), such as 192.168.1.100. The modem router will not accept the IP
address if it is not in this format.
