Used for devices that do not support Border Gateway Protocol (BGP).</p></li>  <li>   <p><code>route.destination-cidr-block</code> - The destination CIDR block. This corresponds to the subnet used in a customer data center.</p></li>  <li>   <p><code>bgp-asn</code> - The BGP Autonomous System Number (ASN) associated with a BGP device.</p></li>  <li>   <p><code>tag</code>:<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      <code>Owner</code> and the value      <code>TeamA</code>, specify      <code>tag:Owner</code> for the filter name and      <code>TeamA</code> for the filter value.    </key></p></li>  <li>   <p><code>tag-key</code> - 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.</p></li>  <li>   <p><code>type</code> - The type of VPN connection. Currently the only supported type is <code>ipsec.1</code>.</p></li>  <li>   <p><code>vpn-connection-id</code> - The ID of the VPN connection.</p></li>  <li>   <p><code>vpn-gateway-id</code> - The ID of a virtual private gateway associated with the VPN connection.</p></li>  <li>   <p><code>transit-gateway-id</code> - The ID of a transit gateway associated with the VPN connection.</p></li> </ul><br>
