Synopsis

Invokes the DescribeRouteTables operation against Amazon Elastic Compute Cloud.

Syntax

Get-EC2RouteTable
-RouteTableId <String[]>
-Filter <Filter[]>

Description

Describes one or more of your route tables. 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 about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Parameters

-Filter <Filter[]>
One or more filters.
  • 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.
  • 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 AWS 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.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=value - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
  • tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag:key=value filter.
  • tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.
  • vpc-id - The ID of the VPC for the route table.
Required?False

Accept pipeline input?False
-RouteTableId <String[]>
One or more route table IDs.Default: Describes all your route tables.
Required?False
Position?1
Accept pipeline input?True (ByValue, 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
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String[] object to this cmdlet for the RouteTableId parameter.

Outputs

This cmdlet returns a collection of RouteTable objects. The service call response (type Amazon.EC2.Model.DescribeRouteTablesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
