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.
Prerequisites
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.
Procedure
- In the top navigation bar, click Networking and then click the Data Center Groups tab.
The list of data center groups appears.
- Click the target data center group.
The
Network Topology view for this data center group opens. The diagram of the current network topology displays the participating VDCs 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 data center 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.
Results
BGP routes are configured on the edge gateway representing the egress point and the universal router of the network fault domain. The configuration does not affect the existing routes on the edge gateway.
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.
