Dynamic Routing
Dynamic Routing allows the iConnect625W router to automatically adjust to physical
changes in the network. It determines the route through which the package travels based
on the least number of hops between the source and the destination. RIP protocol
regularly broadcasts routing information to other routers on the network.
To enable
Dynamic Routing
, follow the steps below.
Step 1
:
From the
Advanced
tab, click the
Dynamic Routing
link provided. The
following page appears:
Step 2:
Check the
Enable RIP
checkbox.
Step 3:
From the
Protocol
drop-down list, select the RIP version as appropriate. The
versions provided are:
RIPv1, RIPv2
and
RIPv1 Compatible
, as shown below.

The same RIP protocol should be used to enable dynamic routing on all routers
on the network.
Step 4:
Check the
Enable Password
checkbox as appropriate.
Step 5:
If you have checked
Enable Password
checkbox, enter a password in the
Password
field. This is an optional field for additional security purposes.
Step 6:
Select the
Direction
for the LAN Group 1 and
MyConnection
interfaces from
the drop-down list. The options are:
None, In, Out
and
Both
.
Step 7:
Click the
Apply
button to apply the settings.
Step 8:
To save your configuration, please refer to the section under
Save / Restart
Menu

The following table lists the
Dynamic Routing
screen fields and their definitions:
Field
Description
Enable RIP
This enables RIP routing on the iConnect625W router.
Protocol
There are three versions of RIP:
1. RIP v1 (UDP Protocol)
2. RIP v2 (multicast protocol)
3. RIP v1-Compatible (UDP Protocol with multicast format)
Routers using RIP v1 or RIP v1-Compatible protocol can talk
to each other, but not to routers using RIP v2 protocol.
Direction determines the means through which RIP routers will
be updated. Select one of the options below.
In
Selecting
In
means that the iConnect625W router will
only incorporate received RIP information.
Out
Selecting
Out
means that the iConnect625W router
will only send out RIP information.
Both
Selecting
Both
means that the iConnect625W router
will incorporate received RIP information and send
out updated RIP information.
Direction
None
Select this option if the function is not required.
Enable Password
Simple password authentication for RIP v2 was defined in RFC
1723. If you intend to use password authentication, you must
enable your password here.
Password
Type the RIPv2 authentication password here. Ensure that all
routers are configured with this password for RIPv2 to work.

Policy Database
The Policy Database page enables you to configure policy routing and QoS. Policy
Database involves routing packets on the basis of various fields in the packet. For
example, the current routing algorithms make decisions based on the destination
address, i.e. only the Destination IP Address and subnet mask are supported.
To configure
Policy Database
, follow the steps below.
Step 1
:
From the
Advanced
tab, click the
Policy Database
link provided. The following
page appears:
Step 2:
Select the incoming traffic interface from the
Ingress Interface
drop-down list.
The options are:
LAN Interfaces, WAN Interfaces, Locally generated
and
Not
Applicable (N/A
).
Step 3:
Select the outgoing connection from the
Destination Interface
drop-down list.
Step 4:
Enter the
DiffServ Code Point
in the field provided. This has to be configured
in conjunction with other fields like the
Source MAC, IP
and
Ingress Interface
.
Step 5:
Enter the Source IP and netmask addresses in the
Source IP
and
Mask
fields.
Step 6:
Select the protocol for the interface from the
Protocol
drop-down list. The
options are:
TCP, UDP, ICMP, None
or
Specify
.
Step 7:
If you have selected the option:
Specify
in the previous step, you have to enter
the protocol number in the box next to
Protocol
.
Step 8:
Enter the
Source
and
Destination ports
in the respective fields.
Step 9:
Enter the source MAC address into the
Source MAC
field.
Step 10:
Enter the
Local Routing Mark
field if
Locally Generated Ingress Interface
was
previously selected.

Step 11:
Select the
Class of Service
from the drop-down list. The options range from
CoS1
to
CoS6
.
Step 12:
Enter the Destination IP and netmask addresses in the
Destination IP
and
Mask
fields.
Step 13:
Click the
Apply
button to apply the settings.
Step 14:
To save your configuration, please refer to the section under

The following table lists the
Policy Database
screen fields and their definitions:
Field
Description
Source Information
Ingress Interface
The incoming traffic interface for a Policy Database rule. The
options include
LAN Interfaces, WAN Interfaces, Locally
generated
(traffic), and
Not Applicable
.
DiffServ Code Point
The DiffServ Code Point or DSCP value ranges from
1
to
255
.
This field cannot be configured alone. Additional fields like
IP,
Source MAC
and/or
Ingress Interface
should be configured at
the same time.
Source IP
The IP address of the traffic source,
Mask
This is the Source IP netmask. This field is mandatory if the
Source IP has been entered.
Protocol
The selections are:
TCP, UDP, ICMP, Specify
and
None
. If
you choose
Specify,
you need to enter the protocol number in
the box next to the
Protocol
field.
This field cannot be configured alone. It has to be configured
along with fields such as the
IP, Source MAC
and/or
Ingress
Interface
. In addition, this field is also mandatory if the
Source
Port
or
Destination Port
has been entered.
Source Port
This is the source protocol port. You cannot configure this
field without entering the protocol first.
Source MAC
This is the MAC address of the traffic source.
