change) to an adjacent router. The adjacent router must be using the same
protocol. Setting this to RIPV1&V2 will give the router the ability to make
routing information exchanges with any adjacent router.
Routing Mode – This parameter allows the router to specify the extent to which
it partakes in the RIP on this port. The options are described below:
1. None – The router will not participate in any RIP exchange with adjacent
routers.
2. Listen – The router will incorporate routing information from adjacent routers,
but will not send its own routing table.
3. Talk – The router will send adjacent routers its own routing table, but will not
incorporate routing information from them.
4. Both – The router will incorporate routing information from adjacent routers,
and will send adjacent routers it's own routing table.
IP Multicasting – This feature enables or disables the router's ability to route IP
Multicast packets from one interface to another (for example, from the LAN ports
to the ISDN port). IP Multicasting is a bandwidth-saving method for transmitting
data to more than one host. IP Multicasting is often used when sending/receiving
audio or video data. When IP Multicasting is enabled, the router will search its
multicast forwarding table and depending on the result of the search will either
forward the packet or add the group to the table. If IP Multicasting is disabled, all
multicast packets received by the router will be dropped, effectively limiting
multicasting to the LAN. The router can also perform DVMRP if this feature is
enabled (see Multicast Protocol below), which allows the DI-308 to share
multicast information with other routers, enabling IP multicasting over the ISDN
port.
Multicast Protocol – If this parameter is set to None, the router will only use the
Internet Group Management Protocol (IGMP), if IP Multicasting is enabled
above. This effectively limits multicast data to the local network. If set to
DVMRP (Distance Vector Multicast Routing Protocol), the router will also use
this protocol to share its multicast information with other routers (much like RIP),
in effect, enabling multicasting on the WAN (ISDN) port.
IGMP Version – Configures the router to use either IGMP version 1 or 2. A
major difference between the two is that version 2 allows the router to
communicate multicast information with other routers (via the ISDN port), even
if the other router isn't using DVMRP.
DHCP Client (LAN) – This feature allows the LAN port to be assigned an IP
address from a DHCP server other than the one in the router. This feature should
be enabled only for special configurations (such as the presence of a cable modem
on the LAN) where you wish the router to work with a device on the network that
must act as a DHCP server. Otherwise, this feature should be kept disabled.
RIP Spoofing (ISDN) – This feature should only be enabled if you have more
than one router on your network and this router is providing your WAN
connection. In this case, if the WAN connection is dropped due to inactivity and
