NAME ^

VM::EC2::VPC::Route -- An entry in a VPC routing table

SYNOPSIS ^

 use VM::EC2;
 my $ec2     = VM::EC2->new(...);
 my $table  = $ec2->describe_route_tables('rtb-123456');
 my @routes = $table->routes;

 foreach my $r (@routes) {
       print $r->destinationCidrBlock,"\n",
             $r->gatewayId,"\n",
             $r->instanceId,"\n",
             $r->instanceOwnerId,"\n",
             $r->networkInterfaceId,"\n",
             $r->state,"\n"
       my $target = $r->target,"\n";  # an instance, gateway or network interface object
}

DESCRIPTION ^

This object supports the EC2 Virtual Private Cloud route interface, and is used to control the routing of packets within and between subnets. Each route has a destination CIDR address block, and a target gateway, instance or network interface that will receive packets whose destination matches the block. Routes are matched in order from the most specific to the most general.

METHODS ^

These object methods are supported:

 destinationCidrBlock -- The CIDR address block used in the destination
                         match. For example 0.0.0/0 for all packets.
 gatewayId            -- The ID of an internet gateway attached to your
                         VPC.
 instanceId           -- The ID of an instance in your VPC to act as the
                         destination for packets. Typically this will be
                         a NAT instance.
 instanceOwnerId      -- The account number of the owner of the instance.
 networkInterfaceId   -- The ID of an Elastic Network Interface to receive
                         packets matching the destination
 state                -- One of "active" or "blackhole". The blackhole state
                         applies when the route's target isn't usable for
                         one reason or another.

In addition, the following convenience methods are provided:

 target       -- Return the target of the route. This method will return
                 a VM::EC2::Instance, VM::EC2::VPC::InternetGateway, or
                 VM::EC2::NetworkInterface object depending on the nature
                 of the target.

 instance     -- If an instance is the target, return the corresponding
                 VM::EC2::Instance object

 gateway      -- If a gateway is the target, return the corresponding
                 VM::EC2::VPC::InternetGateway object.

 network_interface -- If a network interface is the target, return the
                 corresponding VM::EC2::NetworkInterface object.

STRING OVERLOADING ^

When used in a string context, this object will be interpolated as the destinationCidrBlock
