Interconnect

As explained in Google Anthos in Action

An interconnect is a bundled logical link composed of one or more physical links between GDCE and a customer network.

An interconnect is a bundled logical link made from one or more physical links between Google Distributed Cloud Edge (GDCE) and a customer network. Create it only during GDCE site initiation; configure multiple interconnects when high availability is required. section 8.3.1

Use the interconnect as part of GDCE’s edge network resource model:

  • Provision an interconnect attachment on top of the interconnect to isolate a GDCE network from a customer network, optionally using a VRF. section 8.3.1
  • Carry packets through the attachment as untagged traffic or with a customer-specified VLAN ID. section 8.3.1
  • Use a router to configure routing, including BGP peering over an interconnect attachment and route advertisement from selected Pods. section 8.3.1

Inspect the network resource relationships among GDCE networks, subnetworks, interconnects, attachments, and routers. section 8.3.1

How Google Anthos in Action covers it

How deep it goes
Defines the logical link, creation timing, availability pattern, attachments, VLAN handling, and routing integration.
Examples
Uses multiple interconnects for high availability and BGP peering over an interconnect attachment as concrete deployment patterns.
What you can do after
Operate/configure it by provisioning attachments, selecting VLAN tagging, and establishing routing between GDCE and customer networks.
How it connects
Relates to GDCE networks, subnetworks, interconnect attachments, routers, VLANs, VRFs, and BGP peering.
