Router

As explained in Google Anthos in Action

A router is a virtual routing instance that configures routing functions for a network in a GDCE zone.

A router is a virtual routing instance that configures routing functions for a network in a Google Distributed Cloud Edge zone. It can exchange routes between a GDCE network and customer networks through an interconnect attachment or Pod subnet. section 8.3.1

Use a router to:

  • Configure BGP peering over an interconnect attachment between a GDCE network and a customer network. section 8.3.1
  • Configure BGP peering over a Pod subnet so selected Pods can advertise prefixes to GDCE. section 8.3.1
  • Rely on the default behavior that readvertises routes received from subnetworks. section 8.3.1
  • Have system administrators create and maintain the resource; application developers and owners receive view access only. section 8.3.1

Use the network resource model to place the router among GDCE networks, subnetworks, interconnects, and interconnect attachments. section 8.3.1

How Google Anthos in Action covers it

How deep it goes
Defines the routing instance and its peering uses, but does not detail BGP configuration syntax or operational procedures.
Examples
Uses BGP peering over an interconnect attachment or Pod subnet to advertise prefixes.
What it assumes
Requires familiarity with GDCE networks, subnetworks, interconnect attachments, Pod subnets, and BGP peering.
What you can do after
Configure BGP peering and route propagation for a GDCE network.
How it connects
Connects networks, subnetworks, interconnect attachments, Pod subnets, BGP, and route advertisement.
