4.1
Static Routing
When Static Routing is selected as the routing algorithm, the network administrator needs
to manually configure all routes on the router. Any change in the network configuration
would require the administrator to update the information in all affected routers. This can
be a cumbersome task and lead to errors in case of large and complicated networks.
Hence Static routing is typically used for very small networks.
Select Routing →
→ → → Static to configure Static Routing as explained below.
Static Routing
Interface Name Select the interface name (e.g. LAN, WAN1, WAN2) on which route is to
be added.
Destination
Network IP address Enter the destination network IP address for which route is to be added.
Subnet Mask Enter the subnet mask for the destination network IP address.
Gateway IP address
(optional) Enter the Gateway IP address for the route.
After entering all the information press the Apply button. The routes entered will now be
displayed under the Route Entries table. To delete a specific route press the Delete
button next to the specific route entry. In the table, entries with yellow color are active
routes (i.e. the corresponding interface is UP). The entries with grey color are inactive
routes (i.e. the corresponding interface is DOWN).
Click on
View Active Routes , to view the Routing Table with the active routes.
Note: The Gateway IP Address for a static route should be disabled only in case of
PPPoE WAN Link. In all other cases, the Gateway IP Address is mandatory to ensure
proper ARP Resolution.
4.2
Dynamic Routing
Unlike Static routing, Dynamic routing adapts to changes in the network topology. It
automatically learns the routes from all the neighboring routers, selects the most suitable
route to a destination and then spreads the routing information through periodic updates
to all the other routers in the network. The routing updates due to device or link down (or
up) are sent immediately to all routers in the network. The administrator does not need to
manually update any information. There are also mechanisms of self-correction to avoid
