A bridge domain associates its subnets with a VRF, which provides the Layer 3 routing context within a tenant.
A VRF provides the Layer 3 context for the bridge domains associated with it. This relationship enables the subnets in a bridge domain to participate in tenant-specific routing and network segmentation.
-
The VRF provides tenant-specific Layer 3 isolation.
-
The bridge domain associates its subnets with the VRF routing context.
