Vnet 对等互连在 azure 中未被删除

我正在尝试使用 terraform 在 azure 中创建/删除 vnet 对等连接。为了提供一些上下文,有两个 vnet - A 和 B,在两个不同的订阅下,但在同一 AD 中,我可以访问这两个网络。 Vnet A 是静态的,vnetB 是按需创建的。

我能够通过从 vnet B 启动来创建对等互连。但是,当我从 Vnet B 删除对等互连并删除 vNet B 的整个资源组并重新创建资源组和对等互连时,它会显示 -

Error: Cannot create or update peering vnetB. Virtual networks -vnetB and vnetA cannot be peered because address space of the first virtual network overlaps with address space of vnet already peered with the second virtual network. Overlapping address prefixes: 10.2.65.0/25.

我可以看到对等互连未从vnet A. 有没有办法删除这个对等互连?

地形文件:

# It is assumed that A already has a resource group and vnet created
# Access the static A account 
provider "azurerm" {
  alias           = "A"
  subscription_id = "XXXX-XXXX-XXXX"
  features {}
  skip_provider_registration = true
}

data "azurerm_resources" "vnet" {
    resource_group_name = "A-ResourceGroup"
    type = "Microsoft.Network/virtualNetworks"
    provider = azurerm.Aprov
}
resource "azurerm_virtual_network_peering" "A-B" {
  provider = azurerm.Aprov
  name                      = "A-B"
  resource_group_name       = data.azurerm_resources.vnet.resource_group_name
  virtual_network_name      = data.azurerm_resources.vnet.resources[0].name
  remote_virtual_network_id = azurerm_virtual_network.B-vnet.id
}

# Deployment in B Account
provider "azurerm" {
  skip_provider_registration = true
  features {}
}

resource "azurerm_resource_group" "B" {
  name     = "B-peer-1"
  location = "West US"
}

resource "azurerm_virtual_network" "B-vnet" {
  name                = "B-network1"
  resource_group_name = azurerm_resource_group.B.name
  address_space       = ["10.0.1.0/24"]
  location            = "West US"
}

# Add the VNET peering to A account
resource "azurerm_virtual_network_peering" "B-A" {
  name                      = "B-A"
  resource_group_name       = azurerm_resource_group.B.name
  virtual_network_name      = azurerm_virtual_network.B-vnet.name
  remote_virtual_network_id = data.azurerm_resources.vnet.resources[0].id
}

I am trying to create/delete vnet peering connection in azure using terraform. To provide some context, there are two vnets- A and B, under two different subscription but within same AD and I have access to both. Vnet A is static and vnetB is created on-demand.

I am able to create the peering by initiating from vnet B. But when I delete the peering from Vnet B and delete the entire resource group of vNet B and recreate the resource group and peering, it says-

Error: Cannot create or update peering vnetB. Virtual networks -vnetB and vnetA cannot be peered because address space of the first virtual network overlaps with address space of vnet already peered with the second virtual network. Overlapping address prefixes: 10.2.65.0/25.

I can see peering is not deleted from vnet A. Is there a way to delete this peering ?

Terraform file:

# It is assumed that A already has a resource group and vnet created
# Access the static A account 
provider "azurerm" {
  alias           = "A"
  subscription_id = "XXXX-XXXX-XXXX"
  features {}
  skip_provider_registration = true
}

data "azurerm_resources" "vnet" {
    resource_group_name = "A-ResourceGroup"
    type = "Microsoft.Network/virtualNetworks"
    provider = azurerm.Aprov
}
resource "azurerm_virtual_network_peering" "A-B" {
  provider = azurerm.Aprov
  name                      = "A-B"
  resource_group_name       = data.azurerm_resources.vnet.resource_group_name
  virtual_network_name      = data.azurerm_resources.vnet.resources[0].name
  remote_virtual_network_id = azurerm_virtual_network.B-vnet.id
}

# Deployment in B Account
provider "azurerm" {
  skip_provider_registration = true
  features {}
}

resource "azurerm_resource_group" "B" {
  name     = "B-peer-1"
  location = "West US"
}

resource "azurerm_virtual_network" "B-vnet" {
  name                = "B-network1"
  resource_group_name = azurerm_resource_group.B.name
  address_space       = ["10.0.1.0/24"]
  location            = "West US"
}

# Add the VNET peering to A account
resource "azurerm_virtual_network_peering" "B-A" {
  name                      = "B-A"
  resource_group_name       = azurerm_resource_group.B.name
  virtual_network_name      = azurerm_virtual_network.B-vnet.name
  remote_virtual_network_id = data.azurerm_resources.vnet.resources[0].id
}

为了重现您的问题,请在同一区域中创建 VNETA 和 VNET B 并对它们进行对等

VNETA 到 VNETB 对等互连 >
输入图片此处描述

VNETB 到 VNETA 对等互连

在此处输入图像描述

现在我删除了 VNETB,但仍然除非我们不删除或移除对等互连,否则它将与 VNETA 对等互连。

但是,您正在创建相同的 VNETB 或使用不同的名称但具有相同的地址空间,它会说您无法对等,因为您已经在对等中,并且会抛出像您遇到的错误。

输入图片此处描述

您可以从门户本身删除现有对等互连。

在此处输入图像描述

您还可以使用 terraform 命令销毁现有的对等互连<代码>terraform destroy -target nameofpeering

For reproducing your issue create a VNETA and VNET B in the same region and peer them as well

VNETA to VNETB Peering
enter image description here

VNETB to VNETA Peering

enter image description here

Now i deleted the VNETB, But still it will be peer with VNETA untill unless we don't delete or remove peering.

But, you are creating the same VNETB or with different name but with the same address space it will say you can't peer because you already in peer and will throw the error like you are getting.

enter image description here

You can delete the Existing Peering from portal itself.

enter image description here

You can also use terraform command to destroy the existing peering terraform destroy -target nameofpeering
