Fields
id

string (fixed64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.

creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.

name

string

Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

description

string

An optional description of this resource. Provide this property when you create the resource.

region

string

[Output Only] URI of the region where the router resides. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.

network

string

URI of the network to which this router belongs.

interfaces[]

object

Router interfaces. Each interface requires either one linked resource (e.g. linkedVpnTunnel), or IP address and IP address range (e.g. ipRange), or both.

interfaces[].name

string

Name of this interface entry. The name must be 1-63 characters long and comply with RFC1035.

interfaces[].linkedVpnTunnel

string

URI of the linked VPN tunnel. It must be in the same region as the router. Each interface can have at most one linked resource and it could either be a VPN Tunnel or an interconnect attachment.

interfaces[].linkedInterconnectAttachment

string

URI of the linked interconnect attachment. It must be in the same region as the router. Each interface can have at most one linked resource and it could either be a VPN Tunnel or an interconnect attachment.

interfaces[].ipRange

string

IP address and range of the interface. The IP range must be in the RFC3927 link-local IP space. The value must be a CIDR-formatted string, for example: 169.254.0.1/30. NOTE: Do not truncate the address as it represents the IP address of the interface.

interfaces[].managementType

enum

[Output Only] The resource that configures and manages this interface. MANAGED_BY_USER is the default value and can be managed by you or other users; MANAGED_BY_ATTACHMENT is an interface that is configured and managed by Cloud Interconnect, specifically by an InterconnectAttachment of type PARTNER. Google will automatically create, update, and delete this type of interface when the PARTNER InterconnectAttachment is created, updated, or deleted.

bgpPeers[]

object

BGP information that needs to be configured into the routing stack to establish the BGP peering. It must specify peer ASN and either interface name, IP, or peer IP. Please refer to RFC4273.

bgpPeers[].name

string

Name of this BGP peer. The name must be 1-63 characters long and comply with RFC1035.

bgpPeers[].interfaceName

string

Name of the interface the BGP peer is associated with.

bgpPeers[].ipAddress

string

IP address of the interface inside Google Cloud Platform. Only IPv4 is supported.

bgpPeers[].peerIpAddress

string

IP address of the BGP interface outside Google cloud. Only IPv4 is supported.

bgpPeers[].peerAsn

number (uint32 format)

Peer BGP Autonomous System Number (ASN). For VPN use case, this value can be different for every tunnel.

bgpPeers[].advertisedRoutePriority

number (uint32 format)

The priority of routes advertised to this BGP peer. In the case where there is more than one matching route of maximum length, the routes with lowest priority value win.

bgpPeers[].advertiseMode

enum

User-specified flag to indicate which mode to use for advertisement.

bgpPeers[].advertisedGroups[]

enum

User-specified list of prefix groups to advertise in custom mode. This field can only be populated if advertiseMode is CUSTOM and overrides the list defined for the router (in Bgp message). These groups will be advertised in addition to any specified prefixes. Leave this field blank to advertise no custom groups.

bgpPeers[].advertisedIpRanges[]

object

User-specified list of individual IP ranges to advertise in custom mode. This field can only be populated if advertiseMode is CUSTOM and overrides the list defined for the router (in Bgp message). These IP ranges will be advertised in addition to any specified groups. Leave this field blank to advertise no custom IP ranges.

bgpPeers[].advertisedIpRanges[].range

string

The IP range to advertise. The value must be a CIDR-formatted string.
