update IP Address in Vagrant VMs

Question

I have 5 VMs that I spin up using vagrant.

3 load Balancers, and 2 web servers.

---

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.define "lb0" do |lb0|
    lb0.vm.box = "ubuntu/trusty64"
    lb0.vm.hostname = "lb0"
    lb0.vm.network :private_network, ip: "10.11.13.50"
  end
  config.vm.define "lb01" do |lb01|
    lb01.vm.box = "ubuntu/trusty64"
    lb01.vm.hostname = "lb01"
    lb01.vm.network :private_network, ip: "10.11.13.51"
  end
  config.vm.define "lb02" do |lb02|
    lb02.vm.box = "ubuntu/trusty64"
    lb02.vm.hostname = "lb02"
    lb02.vm.network :private_network, ip: "10.11.13.52"
  end

  config.vm.define "web01" do |web01|
    web01.vm.box = "ubuntu/trusty64"
    web01.vm.hostname = "web01"
    web01.vm.network :private_network, ip: "10.11.12.53"
  end

  config.vm.define "web02" do |web02|
    web02.vm.box = "ubuntu/trusty64"
    web02.vm.hostname = "web02"
    web02.vm.network :private_network, ip: "10.11.12.54"
  end
end

I just recently updated the IPs of my load balancers from 10.11.12.x --> 10.11.13.x due to the new requirement.

---

I run vagrant up again, I don't see new IPs updated on my lb0, lb1, and lb2. :( Did I miss anything ?

---

What do I do to update my existing VMs IP without having to destroy them and recreate them ?

After adjusting the new IP in Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.define "lb0" do |lb0|
    lb0.vm.box = "ubuntu/trusty64"
    lb0.vm.hostname = "lb0"
    lb0.vm.network :private_network, ip: "10.11.13.50"
  end
  config.vm.define "lb01" do |lb01|
    lb01.vm.box = "ubuntu/trusty64"
    lb01.vm.hostname = "lb01"
    lb01.vm.network :private_network, ip: "10.11.13.51"
  end
  config.vm.define "lb02" do |lb02|
    lb02.vm.box = "ubuntu/trusty64"
    lb02.vm.hostname = "lb02"
    lb02.vm.network :private_network, ip: "10.11.13.52"
  end

  config.vm.define "web01" do |web01|
    web01.vm.box = "ubuntu/trusty64"
    web01.vm.hostname = "web01"
    web01.vm.network :private_network, ip: "10.11.12.53"
  end

  config.vm.define "web02" do |web02|
    web02.vm.box = "ubuntu/trusty64"
    web02.vm.hostname = "web02"
    web02.vm.network :private_network, ip: "10.11.12.54"
  end
end

I've learn that I have to run vagrant reload

Then, I noticed my IP are updated as expected.
