$table = $ec2->create_route_table($vpc_id)

$table = $ec2->create_route_table(-vpc_id=>$id)

This method creates a new route table within the given VPC and returns a VM::EC2::VPC::RouteTable object. By default, every route table includes a local route that enables traffic to flow within the VPC. You may add additional routes using create_route().

This method can be called using a single argument corresponding to VPC ID for the new route table, or with the named argument form.

Required arguments:

 -vpc_id     A VPC ID or previously-created VM::EC2::VPC object.

$success = $ec2->delete_route_table($route_table_id)

$success = $ec2->delete_route_table(-route_table_id=>$id)

This method deletes the indicated route table and all the route entries within it. It may not be called on the main route table, or if the route table is currently associated with a subnet.

The method can be called with a single argument corresponding to the route table's ID, or using the named form with argument -route_table_id.

@tables = $ec2->describe_route_tables(@route_table_ids)

@tables = $ec2->describe_route_tables(\%filters)

@tables = $ec2->describe_route_tables(-route_table_id=> \@ids, -filter => \%filters);

This method describes all or some of the route tables available to you. You may use the filter to restrict the search to a particular type of route table using one of the filters described at http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeRouteTables.html.

Some of the commonly used filters are:

 vpc-id                  ID of the VPC the route table is in.
 association.subnet-id   ID of the subnet the route table is
                          associated with.
 route.state             State of the route, either 'active' or 'blackhole'
 tag:<key>               Value of a tag

$associationId = $ec2->associate_route_table($subnet_id => $route_table_id)

$associationId = $ec2->associate_route_table(-subnet_id => $id, -route_table_id => $id)

This method associates a route table with a subnet. Both objects must be in the same VPC. You may use either string IDs, or VM::EC2::VPC::RouteTable and VM::EC2::VPC::Subnet objects.

On success, an associationID is returned, which you may use to disassociate the route table from the subnet later. The association ID can also be found by searching through the VM::EC2::VPC::RouteTable object.

Required arguments:

 -subnet_id      The subnet ID or a VM::EC2::VPC::Subnet object.
 -route_table_id The route table ID or a VM::EC2::VPC::RouteTable object.

It may be more convenient to call the VM::EC2::VPC::Subnet->associate_route_table() or VM::EC2::VPC::RouteTable->associate_subnet() methods, which are front ends to this method.

$success = $ec2->dissociate_route_table($association_id)

$success = $ec2->dissociate_route_table(-association_id => $id)

This method disassociates a route table from a subnet. You must provide the association ID (either returned from associate_route_table() or found among the associations() of a RouteTable object). You may use the short single-argument form, or the longer named argument form with the required argument -association_id.

The method returns true on success.

$new_association = $ec2->replace_route_table_association($association_id=>$route_table_id)

$new_association = $ec2->replace_route_table_association(-association_id => $id, -route_table_id => $id)

This method changes the route table associated with a given subnet. You must pass the replacement route table ID and the association ID. To replace the main route table, use its association ID and the ID of the route table you wish to replace it with.

On success, a new associationID is returned.

Required arguments:

 -association_id  The association ID
 -route_table_id   The route table ID or a M::EC2::VPC::RouteTable object.

$success = $ec2->create_route($route_table_id,$destination,$target)

$success = $ec2->create_route(-route_table_id => $id, -destination_cidr_block => $block, -target=>$target)

This method creates a routing rule in a route table within a VPC. It takes three mandatory arguments consisting of the route table, the CIDR address block to match packet destinations against, and a target to route matching packets to. The target may be an internet gateway, a NAT instance, or a network interface ID.

Network packets are routed by matching their destination addresses against a CIDR block. For example, 0.0.0.0/0 matches all addresses, while 10.0.1.0/24 matches 10.0.1.* addresses. When a packet matches more than one rule, the most specific matching routing rule is chosen.

In the named argument form, the following arguments are recognized:

 -route_table_id    The ID of a route table, or a VM::EC2::VPC::RouteTable
                    object.
 -destination_cidr_block
                    The CIDR address block to match against packet destinations.
 -destination       A shorthand version of -destination_cidr_block.
 -target            The destination of matching packets. See below for valid
                    targets.

The -target value can be any one of the following:

 1. A VM::EC2::VPC::InternetGateway object, or an internet gateway ID matching
    the regex /^igw-[0-9a-f]{8}$/
 2. A VM::EC2::Instance object, or an instance ID matching the regex
 /^i-[0-9a-f]{8}$/.
 3. A VM::EC2::NetworkInterface object, or a network interface ID
    matching the regex /^eni-[0-9a-f]{8}$/.
 4. A VM::EC2::VPC::PeeringConnection object, or a VPC peering connection ID
    matching the regex /^pcx-[0-9a-f]{8}$/.

On success, this method returns true.

$success = $ec2->delete_route($route_table_id,$destination_block)

This method deletes a route in the specified routing table. The destination CIDR block is used to indicate which route to delete. On success, the method returns true.

$success = $ec2->replace_route($route_table_id,$destination,$target)

$success = $ec2->replace_route(-route_table_id => $id, -destination_cidr_block => $block, -target=>$target)

This method replaces an existing routing rule in a route table within a VPC. It takes three mandatory arguments consisting of the route table, the CIDR address block to match packet destinations against, and a target to route matching packets to. The target may be an internet gateway, a NAT instance, or a network interface ID.

Network packets are routed by matching their destination addresses against a CIDR block. For example, 0.0.0.0/0 matches all addresses, while 10.0.1.0/24 matches 10.0.1.* addresses. When a packet matches more than one rule, the most specific matching routing rule is chosen.

In the named argument form, the following arguments are recognized:

 -route_table_id    The ID of a route table, or a VM::EC2::VPC::RouteTable
                    object.
 -destination_cidr_block
                    The CIDR address block to match against packet destinations.
 -destination       A shorthand version of -destination_cidr_block.
 -target            The destination of matching packets. See below for valid
                    targets.

The -target value can be any one of the following:

 1. A VM::EC2::VPC::InternetGateway object, or an internet gateway ID matching
    the regex /^igw-[0-9a-f]{8}$/
 2. A VM::EC2::Instance object, or an instance ID matching the regex
 /^i-[0-9a-f]{8}$/.
 3. A VM::EC2::NetworkInterface object, or a network interface ID
    matching the regex /^eni-[0-9a-f]{8}$/.
 4. A VM::EC2::VPC::PeeringConnection object, or a VPC peering connection ID
    matching the regex /^pcx-[0-9a-f]{8}$/.

On success, this method returns true.
