In virtual data center groups with common egress configurations, you can add a secondary egress point, which acts as a standby egress point for fault tolerance scenarios.
Apart from the edge gateway that acts as an active egress point, you must have at least one more edge gateway in any of the virtual data centers that are participating in the group.
- From the main menu (), select Datacenter Groups.
The list of data center groups displays in a card view.
- In the card of the target data center group, click Details.
You are redirected to the Network Topology view for this data center group. You can see a diagram of the current network topology, which depicts the participating virtual data centers with their network fault domains, the egress points if configured, and the traffic routes.
- Click Add stand-by egress point.
The Add Stand-by Egress Point page opens providing a list of the unused edge gateways that belong to the participating virtual data centers. The edge gateway that is in use by the active egress point in this virtual datacenter group is not displayed.
- Select the edge gateway that you want to act as a stand-by egress point for this data center group, and click Add.
BGP routes are configured on the edge gateway representing the egress point and the universal router of the virtual data center group. Existing routes on the edge gateway are not affected.
The diagram of the network topology is updated with the newly added egress point. The traffic from the participating virtual data centers to the Internet in fault tolerance scenarios is represented with a dashed blue line.
