Overview of procedures to configure Lumen Cloud Connect

  1. Sign into Azure portal
  2. Create a new Azure ExpressRoute circuit
  3. View the circuits and properties
  4. Request Lumen Cloud Connect service
  5. Service Key creation
  6. Lumen provisions Cloud Connect to Microsoft Azure ExpressRoute
  7. Configure Microsoft Peering

Procedure to Configure Lumen Cloud Connect

Sign into Azure Portal

  • Sign into Azure portal with a user who has the right permissions

azure-portal

Create a new Azure ExpressRoute Circuit

  • After clicking ExpressRoute, portal will display ‘Create ExpressRoute circuit’ blade. When filling in the values on this blade, here are some helpful tips:
  • Select the Provider as CenturyLink Cloud Connect, see below:

creates-new-expressroute-circuit

  • Select the appropriate ExpressRoute location.
    • For Example: Silicon Valley = San Jose; Washington DC = Ashburn
  • Specify the correct SKU for Tier and Data Metering:
    • SKU / Tier determines whether an ExpressRoute standard or an ExpressRoute premium add-on is enabled.
    • Billing Model / Data Metering determines the billing type that Microsoft will use to bill the customer directly for ExpressRoute.
    • Note that the billing type can be changed from Metered to Unlimited, but may not be changed from Unlimited to Metered
  • Select the appropriate Subscription and Resource Group
    • User must have a subscription type set, such as Pay-As-You-Go
    • A Resource group is a collection of resources that share the same lifecycle, permissions, and policies.
    • Additional information can be found here

Important:
Please be aware that the ‘Peering Location’ indicates the physical location where you are peering with Microsoft. This is not linked to "Location" property, which refers to the geography where the Azure Network Resource Provider is located.

View the circuits and properties

  • Create an ExpressRoute circuit by selecting the option to create a new resource: expressroute-new-resource
  • View all created ExpressRoute circuits by selecting All resources on the left-side menu: expressroute-view-circuits expressroute-view-circuits-2

Request Lumen Cloud Connect service

  • To order a Lumen Cloud Connect, contact your Lumen Account Representative
    • Contact your Lumen account rep to assist in ordering a Cloud Connect to ExpressRoute.

    • Information needed by Lumen to complete connection:

      • MSFT Azure ExpressRoute Service Key completed during Lumen Provisioning steps
      • Customer requests Cloud Connect to the appropriate Azure ExpressRoute Location
      • Bandwidth of eLynk Connection requested (typically matches ExpressRoute speed)
        Note: eLynk Cloud Connect has max bandwidth of 3Gb. If eLynk is 3Gb, a 5GB ExpressRoute port is required (the next higher increment).
    • What Azure service(s) are you connecting to:

      • Azure Private Peering (Compute/IaaS)
      • Microsoft Peering (Azure PaaS, Office 365, Dynamics 365, etc.)
    • Cloud Connect contractual term length

      • i.e. 1year, 3year, etc.

Service Key creation

  • Upon request, customer sends the service key to Lumen for Cloud Connect provisioning

    • The Lumen Technical Design Engineer will request the ExpressRoute Service Key from the customer prior to provisioning but after Order Entry.
    • On this blade, Provider status provides information on the current state of provisioning on the service-provider (Lumen) side. Circuit status provides the state on the Microsoft side.

    expressroute-service-key

    • When creating a new ExpressRoute circuit, the circuit will be in the following state:
      • Provider status: Not provisioned
      • Circuit status: Enabled
    • The circuit will change to the following state when the connectivity provider (Lumen) is in the process of enabling it:
      • Provider status: Provisioning
      • Circuit status: Enabled
    • To be able to use an ExpressRoute circuit, the circuit must be in the following state:
      • Provider status: Provisioned
      • Circuit status: Enabled

Lumen provisions Cloud Connect to Microsoft Azure ExpressRoute

  • Upon network order submission, Lumen will provision a Layer 2 eLynk connection to the requested ExpressRoute Location
    • Turn up of Layer 2 eLynk service to local ExpressRoute interconnect point
      • Layer 2 VLAN(s) between Lumen and Microsoft and Lumen and the customer will be configured by Lumen
  • Lumen completes configuration and provides Customer with necessary layer 2 VLAN information for CPE and Azure configurations to be completed by the customer.
    • Customer to configure appropriate Layer 2 VLAN tagging on CPE utilizing Q-in-Q tagging configuration.  It is important to note that the Lumen EtherType specification of double-tagged frames is for both inner and outer tags to be 0x8100.
    • Turn up of Layer 3 BGP/routing between customer and Azure
      • Layer 3/BGP will be configured by the customer on the customer router and on Azure side via the customers Azure portal account.

Configure Microsoft Peering

Please refer to Microsoft Peering in What is ExpressRoute knowledge article to learn more on Microsoft Peering.

  • To be able to successfully connect to services through Microsoft peering, you must complete the following configuration steps:
    • You must have an active ExpressRoute circuit that has Microsoft peering provisioned You can use the following instructions to accomplish these tasks:
      • Create an ExpressRoute circuit and have the circuit enabled by your connectivity provider before you proceed. The ExpressRoute circuit must be in a provisioned and enabled state.
      • Have your connectivity provider provision Microsoft peering for your circuit.
    • You must create and configure a route filter
      • Identify the services you wish to consume through Microsoft peering
      • Identify the list of BGP community values associated with the services
      • Create a rule to allow the prefix list matching the BGP community values
    • You must attach the route filter to the ExpressRoute circuit
      Please refer to Quickstart: Create and modify an ExpressRoute circuit for the latest information from Microsoft.
