Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) DescribeRouteTables API operation.

Syntax

Get-EC2RouteTable
-RouteTableId <String[]>
-Filter <Filter[]>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonEC2Config>

Description

Describes your route tables. The default is to describe all your route tables. Alternatively, you can specify specific route table IDs or filter the results to include only the route tables that match specific criteria. Each subnet in your VPC must be associated with a route table. If a subnet is not explicitly associated with any route table, it is implicitly associated with the main route table. This command does not return the subnet ID for implicit associations. For more information, see Route tables in the Amazon VPC User Guide.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-ClientConfig <AmazonEC2Config>
Amazon.PowerShell.Cmdlets.EC2.AmazonEC2ClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Filter <Filter[]>
The filters.
  • association.gateway-id - The ID of the gateway involved in the association.
  • association.route-table-association-id - The ID of an association ID for the route table.
  • association.route-table-id - The ID of the route table involved in the association.
  • association.subnet-id - The ID of the subnet involved in the association.
  • association.main - Indicates whether the route table is the main route table for the VPC (true | false). Route tables that do not have an association ID are not returned in the response.
  • owner-id - The ID of the Amazon Web Services account that owns the route table.
  • route-table-id - The ID of the route table.
  • route.destination-cidr-block - The IPv4 CIDR range specified in a route in the table.
  • route.destination-ipv6-cidr-block - The IPv6 CIDR range specified in a route in the route table.
  • route.destination-prefix-list-id - The ID (prefix) of the Amazon Web Services service specified in a route in the table.
  • route.egress-only-internet-gateway-id - The ID of an egress-only Internet gateway specified in a route in the route table.
  • route.gateway-id - The ID of a gateway specified in a route in the table.
  • route.instance-id - The ID of an instance specified in a route in the table.
  • route.nat-gateway-id - The ID of a NAT gateway.
  • route.transit-gateway-id - The ID of a transit gateway.
  • route.origin - Describes how the route was created. CreateRouteTable indicates that the route was automatically created when the route table was created; CreateRoute indicates that the route was manually added to the route table; EnableVgwRoutePropagation indicates that the route was propagated by route propagation.
  • route.state - The state of a route in the route table (active | blackhole). The blackhole state indicates that the route's target isn't available (for example, the specified gateway isn't attached to the VPC, the specified NAT instance has been terminated, and so on).
  • route.vpc-peering-connection-id - The ID of a VPC peering connection specified in a route in the table.
  • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.
  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.
  • vpc-id - The ID of the VPC for the route table.
Required?False
Position?2
Accept pipeline input?True (ByPropertyName)
AliasesFilters
-MaxResult <Int32>
The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the RouteTableId parameter. The -PassThru parameter is deprecated, use -Select '^RouteTableId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RouteTableId <String[]>
The IDs of the route tables.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesRouteTableIds
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'RouteTables'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeRouteTablesResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeRouteTablesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
