The design contains community components as follows.
Cloud service supplier configuration
- Router- The on-prem setup makes use of two pairs of routers positioned in two areas.

Cross-Cloud Interconnect configuration
- VLAN attachments – Cloud Interconnect is a 10/100 GigabitEthernet trunk. Customers configure VLAN attachments with a VLAN ID that’s related to a cloud router.
- Cloud Router might be configured to announce a restricted subset of prefixes utilizing customized route commercials, or it may be configured to announce all recognized subnet routes to its BGP peer.
As soon as configurations are full, your exterior environments can talk with Google Cloud.
Community Connectivity Heart
Community Connectivity Heart permits you to join your on-premises, Google Cloud, and different cloud enterprise networks via a single, centralized logical hub on Google Cloud, connecting a number of on-prem websites and different clouds over the Google Cloud community spine.
