Private
This parameter determines if the device will include the route to
this remote node in its RIP broadcasts. If set to Yes, this route is
kept private and not included in RIP broadcast. If No, the route to
this remote node will be propagated to other hosts through RIP
broadcasts.
Advanced Setup
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 device will broadcast its routing
table periodically.
When set to
Both
or
In Only
, the device will incorporate RIP
information that it receives.
When set to
None
, the device 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 device 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 network-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 inter operability
between IGMP version 2 and version 1, please see sections 4 and 5
of RFC 2236.
