In local data center groups configurations, you can add a secondary egress point, which acts as a stand-by egress point for fault tolerance scenarios.
- 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 appears dimmed.
- 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 network fault domain. The configuration does not affect the existing routes on the edge gateway.
The newly added egress point appears in the network topology diagram. A dashed blue line represents the traffic from the participating virtual data centers to the Internet in fault tolerance scenarios.
