RUTX11 Routing
The information in this page is updated in accordance with firmware version RUTX_R_00.07.08.3.
Summary
The Routing page is used to set up static and dynamic routes, routing tables and rules.
This manual page provides an overview of the Routing windows in RUTX11 devices.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.
Static Routes
Routes ensure that network traffic finds its path to a specified host or network, both in local and remote network scenarios. Static routes are simply fixed routing entries in the routing table(s).
This section provides the possibility to configure custom static routes.
Static IPv4 Routes
The Static IPv4 Routes section displays a list of user defined static IPv4 routes and provides the possibility to add and configure new ones. The list is empty by default.
To add a new route and begin editing, simply click the 'Add' button. Refer to the table below for information on static route configuration fields.
Field | Value | Description |
---|---|---|
Interface | network interface; default: lan | Network interface of the target network. |
Target* | ip4; default: none | Destination network address. |
IPv4-Netmask* | netmask; default: none | A netmask is used to divide an IP address into sub-networks (subnets). Combined together, the 'Netmask' and 'Target' values define the exact destination network or IP address to which this route applies. |
IPv4-Gateway | ip4; default: none | A gateway can be any machine in a network that is capable of serving as an access point to another network. Traffic that matches this route will be directed over the IP address specified in this field. |
Metric | integer [0..255]; default: none | The metric value acts as a measurement of priority. If a packet about to be routed matches two or more rules, the one with the lower metric is applied. |
MTU | integer [64..9000]; default: 1500 | Sets the maximum transmission unit (MTU) size. It is the largest size of a protocol data unit (PDU) that can be transmitted in a single network layer transaction. |
Route Type | unicast | local | broadcast | multicast | unreachable | prohibit | backhole | anycast | -- custom -- ; default: unicast | Selects route type. Each type specifies a different behavior for the route:

*Additional notes on 'Target' & 'Netmask' fields:
You can define a rule that applies to a single IP like this:

Dynamic Routes
Dynamic Routing provides the possibility to route data based on current network or device state instead of relying on static entries in the routing table. The RUTX11 device supports these dynamic routing protocols:

- OSPF (Open Shortest Path First)
- EIGRP (Enhanced Interior Gateway Routing Protocol)
- NHRP (Next Hop Resolution Protocol)
Each protocol is described in the sections below.

The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions.

RIP implements the split horizon, route poisoning and holddown mechanisms to prevent incorrect routing information from being propagated.
