On-prem with redundancy and multiple VPCs

Reserved on-prem connection via two Cloud Interconnect private connections to a single RI with two or more cloud networks without network connectivity between them.

The network topology is presented on the diagram in the following configuration:

• On-Prem client with two local subnets: subnet-c1 and subnet-c2.
• The on-prem network hardware connects to the Yandex Cloud network hardware via Cloud Interconnect.
• Two private connections, prc-m9 and prc-nord, established via two points of presence, M9 and NORD, connect to RI in Yandex Cloud.
• Two virtual networks connect to RI on the Yandex Cloud side:
  • Net-1 comprised of three subnets: subnet-a1, subnet-b1, and subnet-d1.
  • Net-2 comprised of three subnets: subnet-a2, subnet-b2, and subnet-d2.

This topology enables network connectivity between:

• On-Prem subnets and Net-1 VPC subnets subnet-a1, subnet-b1, and subnet-d1.
• On-Prem subnets and Net-2 VPC subnets subnet-a2, subnet-b2, and subnet-d2.

In case of failure of any of the private connections above, all network traffic will be automatically switched over to the remaining private connection.

This topology enables network connectivity between Net-1 and Net-2 virtual networks subnets.
