EC2 Describe Route Tables - BlinkOps Documentation

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, see Route tables in the Amazon Virtual Private Cloud User Guide.

Basic Parameters

Parameter	Description
AWS Region(s)	Enter the desired AWS Region(s). To execute the action in multiple regions, provide a comma-separated list. For example: `us-east-1,eu-west-2`. If you wish to run the action in all available regions, use the asterisk symbol (`*`) instead.
Route Table IDs	One or more route table IDs. Default: Describes all your route tables.

Advanced Parameters

Parameter	Description
Disable XML To JSON Auto Convert	When checked, XML responses are not automatically converted into JSON format.
Dry Run	Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.
Filters	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. - `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 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.
Max Results	The maximum number of results to return with a single call. To retrieve the remaining results, make another call with the returned `nextToken` value.
Next Token	The token for the next page of results.
