Question

A network engineer is deploying Cisco Catalyst SD-WAN Cloud OnRamp for Multicloud into AWS. The design must connect multiple SD-WAN branch sites to workload VPCs across two AWS regions, while allowing the SD-WAN cloud gateway capacity to grow automatically as branch throughput increases without manual instance provisioning. Which configuration approach in vManage/Cloud OnRamp best meets these requirements?

Accepted Answer

Deploy Cisco Catalyst 8000V cloud gateways using the Transit Gateway (TGW) connection model with autoscale enabled, and map workload VPCs to the gateway via tag-based host VPC discovery

Answer

Deploy a single Cisco Catalyst 8000V in each workload VPC and rely on VPC peering between regions for east/west reachability

Answer

Configure static IPsec tunnels from each branch router directly to every workload VPC's virtual private gateway, disabling Cloud OnRamp automation

Answer

Deploy the cloud gateway using the Cloud OnRamp for SaaS workflow and attach workload VPCs through Direct Connect private VIFs
