DESCRIPTION
RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. Use this field to control how much routing information the
AMG1312-T Series sends and receives on the subnet.
Select the RIP direction from None, Both, In Only and Out Only.
This field is not configurable if you select None in the RIP Direction field.
Select the RIP version from RIP-1, RIP2-B and RIP2-M.
Multicast packets are sent to a group of computers on the LAN and are an alternative
to unicast packets (packets sent to one computer) and broadcast packets (packets
sent to every computer).
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a multicast group. The AMG1312-T Series supports IGMP-v1, IGMP-
v2 and IGMP-v3. Select None to disable it.
Select the version of MLD proxy (v1 or v2) to have the AMG1312-T Series act as for
this connection. This allows the AMG1312-T Series to get subscription information and
maintain a joined member list for each multicast group. It can reduce multicast traffic
significantly. Select None to turn off MLD proxy.
Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or
data traffic. Select UBR With PCR (Unspecified Bit Rate) for applications that are
non-time sensitive, such as e-mail. Select Realtime VBR (real-time Variable Bit
Rate) type for applications with bursty connections that require closely controlled
delay and delay variation. Select Non Realtime VBR (non real-time Variable Bit
Rate) type for connections that do not require closely controlled delay and delay
variation.
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell
Rate (PCR). This is the maximum rate at which the sender can send cells. Type the
PCR here.
