SM Router Mode - Static Route |
When Enabled, it allows the operator to create static routes that will apply to both the Wireless and Ethernet interface of the SM. This allows operators to configure a custom table of explicit paths between networks. Static routing is often used as a method to reduce the overhead of processing dynamic routes through a network when the specific path is known (or, it is simpler to define a specific path). Static routing is also used as a backup when dynamic routing protocols fail to complete a route from one network to another. In router mode, the Static Routes table is referenced by the SM to forward/filter packets to a particular destination configured by the user based on the IP addressing information contained in the table. Since static routes do not change with network changes, it is recommended to only use static routes for simple network paths which are not prone to frequent changes (requiring updates to the routes configured on the ePMP SM). It is important to consider each hop in a static route’s path to ensure that the routing equipment has been configured to statically or dynamically route packets to the proper destination. Otherwise, the network communication will fail. Note Network Address Translation (NAT) is not performed when the SM is in Router mode. |

SM Router Mode - IP Aliases |
When Enabled, IP aliases allow the operator to associate more than one IP address to the Ethernet interface of the SM. This configuration of multiple IP addresses for the SM’s Ethernet interface allows connections to multiple networks, often used as a mechanism for management access to the device from a convenient networking path. |
