Host Routes

Host routes let you insert entries into the Oracle® Enterprise Session Border Controller's routing table. These routes affect traffic that originates at the Oracle® Enterprise Session Border Controller’s host process. Host routes are used primarily for steering management traffic to the correct network.

When traffic is destined for a network that is not explicitly defined on a Oracle® Enterprise Session Border Controller, the default gateway (located in the system-config) is used. If you try to route traffic to a specific destination that is not accessible through the default gateway, you need to add a host route. Host routes can be thought of as a default gateway override.

Certain SIP configurations require that the default gateway is located on a media interface. In this scenario, if management applications are located on a network connected to an administrative network, you will need to add a host route for management connectivity.

When source-based routing is used, the default gateway must exist on a media interface. Host routes might be needed to reach management applications connected to a management port in this kind of situation as well.

Note:

Do not configure a host-route > gateway with an address already used for any existing network-interface > gateway.
