DESCRIPTION
RIP Direction
RIP (Routing Information Protocol) allows a router to exchange routing information with other
routers. The
RIP Direction
field controls the sending and receiving of RIP packets.
Choose
Both, None, In Only
or
Out Only.
When set to
Both
or
Out Only,
the 1500WR Wireless
Router will broadcast its routing table periodically.
When set to
Both
or
In Only,
the 1500WR Wireless Router will incorporate RIP information that it
receives.
When set to
None,
the 1500WR Wireless Router will not send any RIP packets and will ignore any
RIP packets received.
By default,
RIP Direction
is set to
Both.
RIP Version
The
RIP Version
field controls the format and the broadcasting method of the RIP packets that the
1500WR Wireless Router sends (it recognizes both formats when receiving).
Choose
RIP-1, RIP-2B
or
RIP-2M.
RIP-1
is universally supported; but
RIP-2
carries more information. RIP-1 is probably adequate for
most networks, unless you have an unusual network topology. Both
RIP-2B
and
RIP-2M
sends the
routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-
2M uses multicasting. Multicasting can reduce the load on non-router machines since they generally
do not listen to the RIP multicast address and so will not receive the RIP packets. However, if one
router uses multicasting, then all routers on your network must use multicasting, also. By default,
the
RIP Version
field is set to
RIP-1
.
Multicast
Choose
None
(default),
IGMP-V1
or
IGMP-V2.
IGMP (Internet Group Multicast Protocol) is a
session-layer protocol used to establish membership in a Multicast group - it is not used to carry
user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP
version 1 is still in wide use. If you would like to read more detailed information about interoperability
between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast
packets that enable a computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE or
PPTP, NetBIOS packets cause unwanted calls.
Allow From WAN
to LAN
Select this option to forward NetBIOS packets from the WAN port to the LAN port.
Allow Trigger Dial
Select this option to allow NetBIOS packets to initiate calls.
