DRG functionality has been expanded to include the following capabilities:
- You can attach a DRG to more than one VCN to provide inter-VCN network connectivity. VCNs can be in the same or different tenancies.
- You can now assign a different route table and policy to each network resource attached to your DRG enabling granular routing control. For instance, by connecting all your VCNs and on-premises networks to a single DRG used as a “Hub,” you have a single central gateway to configure traffic routing and Layer 3 isolation. One possible use case of routing policy is directing all traffic passing thru the DRG to a network virtual appliance or firewall.
- Your on-premises network connected to a DRG in one region can access networks connected to a DRG in a different region using a remote peering connection (RPC).
- You can now enable equal cost multi-path (ECMP) routing towards your IPSec VPN and FastConnect connections to support active-active scenarios. ECMP is controlled on a per route table basis.
- Remote peering connections can now connect DRGs in the same region or different tenancies.
