Overview: Managing dynamic discovery of remote endpoints

Dynamic discovery is a process through which the BIG-IP identifies and adds remote endpoints automatically. The process occurs when the BIG-IP receives traffic that is matched by a virtual server with an iSession profile, but does not recognize the remote destination. When a BIG-IP receives a request destined for a location on the network behind the BIG-IP on the other side of the WAN, the first BIG-IP sends out TCP options or ICMP probes to discover, authenticate, and initiate communication with the new remote endpoint.

Note: A TCP request from the client to the server is the action that triggers discovery, not a ping between two endpoints.

Task Summary

Perform these tasks to manage dynamic discovery of remote endpoints.

Task list

Verifying subnet discovery

After sending traffic between two configured BIG-IP devices, you can perform this task to verify that BIG-IP has discovered the remote endpoint.
  1. On the Main tab, click Symmetric Optimization > Remote Endpoints.
  2. Verify that the status indicator is green, and the IP address is correct for the remote endpoint you are checking.

Modifying dynamic discovery of remote endpoints

You can modify the dynamic discovery settings, such as specifying the number and types of probe messages, or disabling dynamic discovery.
  1. On the Main tab, click Symmetric Optimization > Remote Endpoints > Discovery.
  2. From the Dynamic Discovery list, select Advanced to view all the settings.
  3. Modify the settings, as required.
  4. Click Update to save changes.
