TW-H6W1IR ISDN Remote Router
38 Configuration and
Management
?? 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 TW-H6W1IR to share multicast information with
other routers, enabling IP multicasting over the ISDN port.
