Configuration Example with ExtremeCloud IQ and Redundancy provides an example of a redundant Tunnel Concentrator deployment with ExtremeCloud IQ as the management application. The example provides sample IP address assignments for the deployment.
With this example, Tunnel Concentrator is installed on Universal Compute Platform 4120C hardware, which supports up to three instances per server.
IP Address Assignments provides more information on the IP address assignments.
| Universal Compute Platform (UCP) on 4120C | Management IP (for UCP) | Tunnel Concentrator Instances | Tunnel Concentrator Licensing IPs | GRE Termination Points (per instance) | VRRP IPs |
|---|---|---|---|---|---|
| UCP-01-DC1 | 10.224.113.31:5825 | XIQTC-1 | 10.224.113.41:5825 | 10.224.113.51 (primary) | 10.224.113.61 |
| XIQTC-2 | 10.224.113.42:5825 | 10.224.113.52 (primary) | 10.224.113.62 | ||
| XIQTC-3 | 10.224.113.43:5825 | 10.224.113.53 (backup) | 10.224.113.63 | ||
| UCP-02-DC1 | 10.224.113.32:5825 | XIQTC-1 | 10.224.113.45:5825 | 10.224.113.55 (backup) | 10.224.113.61 |
| XIQTC-2 | 10.224.113.46:5825 | 10.224.113.56 (backup) | 10.224.113.62 | ||
| XIQTC-3 | 10.224.113.47:5825 | 10.224.113.57 (primary) | 10.224.113.63 |
The following details provide information on how to configure each column:
Universal Compute Platform—This example uses two hardware servers.
Management IP (for Universal Compute Platform)—This IP address is configured on Universal Compute Platform as part of your prerequisites for a Tunnel Concentrator installation. This IP address allows administrators to access the Universal Compute Platform user interface.
Tunnel Concentrator Instances—The engine instance gets assigned automatically when you install the Tunnel Concentrator application.
Tunnel Concentrator Licensing IPs—During Tunnel Concentrator installation, this address is configured as the Assigned Virtual IP Address and is required to license the application. After licensing is complete, you have the option to unconfigure this address and use ExtremeCloud IQ to access the Tunnel Concentrator user interface.
GRE Termination Points (per instance)—Configure this address on ExtremeCloud IQ as part of the Tunnel Concentrator service configuration. Select the Redundant Tunnel Concentrator option and assign these addresses to the IP Address field for the Primary Tunnel Concentrator and Backup Tunnel Concentrator instances. The (primary) and (backup) designation in the table indicates whether the instance is configured as the primary or backup Tunnel Concentrator.
Note
For each service, assign one Tunnel Concentrator instance from each Universal Compute Platform server. With this example, you must configure three services, which reflects the three High Availability pairs.VRRP IPs— On ExtremeCloud IQ, during the Tunnel Concentrator service configuration, assign the VRRP IP address to the Tunnel IP Address field for the redundant High Availability pair.
