The correct option to configure the Session Border Controller (SBC) to perform load balancing between two downstream SIP proxies is A. session-router and router-group.
Here's a detailed explanation of why this is the correct option:
In a load balancing configuration, the SBC distributes incoming SIP traffic across multiple downstream SIP proxies to ensure that no single proxy is overloaded with traffic. To set up load balancing on an SBC, you need to configure the following elements:
Session-router: The session-router is the component of the SBC that determines how incoming SIP sessions should be handled. In a load balancing configuration, the session-router needs to be configured to distribute incoming sessions across multiple router-groups.
Router-group: A router-group is a collection of SIP proxies that are configured to handle incoming sessions. In a load balancing configuration, you need to create at least two router-groups, each containing one of the downstream SIP proxies.
To configure these elements, you need to perform the following steps:
Log in to the SBC's web-based management interface.
Navigate to the "Configuration" tab.
Click on the "Session Router" option in the left-hand menu.
Click on the "New" button to create a new session-router.
Give the session-router a name and configure its settings as desired.
Click on the "Router Group" tab to create a new router-group.
Click on the "New" button to create a new router-group.
Give the router-group a name and add the IP address or hostname of the first downstream SIP proxy to the "Members" field.
Click on the "Save" button to save the router-group.
Repeat steps 7-9 for the second downstream SIP proxy, but add it to a new router-group.
Go back to the "Session Router" tab and click on the "Edit" button next to the session-router you created earlier.
Click on the "Groups" tab and add both router-groups to the "Router Groups" field.
Save the session-router.
Once you've completed these steps, the SBC will distribute incoming SIP sessions across the two downstream SIP proxies in a load-balanced fashion.
