APIC
Multi-Site Setup

Reference

This page is a reference and takeway for you to understand the initial Day 0 configuration required on an APIC within a Site prior to adding it to the Multi-Site Orchestrator.

Simply, you must define Access Policies for Spine interfaces much like was done earlier in this lab. Then, you must create an Intrasite/Intersite Profile that is used for various purposes such as VTEP addresses, BGP communities for EVPN, etc.

Step 1 - Create VLAN Pool

Navigate to Access Policies to create a VLAN pool for a physical domain by clicking:

  1. Fabric
  2. Access Policies
  3. Expand Pools by clicking the toggle arrow (>)
  4. Right-click on VLAN
  5. Click Create VLAN Pool

In the Create VLAN Pool popup:

  1. We named the VLAN Pool: msite
  2. Ensure Static Allocation is selected
  3. Then click the plus sign (+) button to add the VLAN pool range

    4. After clicking on the the plus sign (+) then you can enter your VLAN range for this pool:
  4. VLAN Range: 4 - 4
  5. Click OK

  6. Click Submit

Step 2 - Create AEP

To create an AEP, naviage to Attachable Access Entity Profiles by clicking:

  1. Fabric
  2. Access Policies
  3. Expand Policies by clicking the toggle arrow (>)
  4. Expand Global by clicking the toggle arrow (>)
  5. Right-click on Attachable Access Entity Profiles
  6. Click Create Attachable Access Entity Profile

    7. Create an AEP for your Physical / Layer 2 Domain that will associate to your Layer 2 interfaces. In the Create Physical Domain popup:
  7. Name the AEP: msite-aep
  8. Click Next

    9. You have not created the interface policy to associate this AEP yet, so you're going to skip Step 2 and just click Finish.

Step 3 - Create L3 Domain

To create an External Routed Domain, naviage to L3 Domains by clicking:

  1. Fabric
  2. Access Policies
  3. In the left navigation pane, all the way the bottom, expand Physical and External Domains by clicking the toggle arrow (>)
  4. Right-click on L3 Domains/li>
  5. Click Create Layer 3 Domain

    6. In the Create Layer 3 Domain popup:
  6. Name the Layer 3 Domain: msite-l3
  7. Foe the AEP, select the msite-aep
  8. For the VLAN Pool, select the msite vlan pool
  9. Click Submit

Step 4 - Create Spine Policy Group

To create an Spine Policy Group, naviage to Policy Groups by clicking:

  1. Fabric
  2. Access Policies
  3. Expand Interfaces by clicking the toggle arrow (>)
  4. Expand Spine Interfaces by clicking the toggle arrow (>)
  5. Right-click on Policy Groups
  6. Click Create Spine Access Port Policy Group

    7. In the Create Spine Access Port Policy Group popup:
  7. Name the Policy Group: msite-polgrp
  8. For Link Level Policy, select or create a 40G policy
  9. For CDP Policy, select or create an enabled policy
  10. For the AEP, select the msite-aep
  11. Click Submit

Step 5 - Create Spine Interface Profile

To create an Spine Interface Profile, naviage to Interface Profiles by clicking:

  1. Fabric
  2. Access Policies
  3. Expand Interfaces by clicking the toggle arrow (>)
  4. Expand Spine Interfaces by clicking the toggle arrow (>)
  5. Right-click on Profiles
  6. Click Create Spine Interface Profile

    7. In the Create Spine Interface Profile popup:
  7. Name the Policy Group: msite-intprof
  8. Click the plus button (+) for Interface Selectors

    9. In the Create Spine Access Port Selector popup:
  9. Name the Port Selector: 1 (for the Spine port used)
  10. For Interface IDs, set to Spine port (for our fabric, that was 1/1)
  11. For Interface Policy Group , the Policy Group from the previous section is used, msite-polgrp
  12. Click OK
  13. Then, once back at the Create Spine Interface Profile, click Submit

Step 6 - Create Spine Switch Profile

To create an Spine Profile, naviage to Switch Profiles by clicking:

  1. Fabric
  2. Access Policies
  3. Expand Switches by clicking the toggle arrow (>)
  4. Expand Spine Switches by clicking the toggle arrow (>)
  5. Right-click on Profiles
  6. Click Create Spine Profile

    7. In the Create Spine Profile popup:
  7. Name the Policy Group: Spines
  8. Click the plus button (+) for Spines Selectors and add Spines S1 (101) and S2 (102) with their corresponding names
  9. Click Next

    10. In the Create Spine Profile popup:
  10. Select the Interface Profile created for the Spine Multi-Site connections. We called ours msite-intprof.
  11. Click Finish

Step 7 - Create Infra Tenant Intersite Profile

In the infra tenant:

  1. Expand Policies by clicking the toggle arrow (>)
  2. Expand Protocols by clicking the toggle arrow (>)
  3. Right-click on Fabric Ext Connection Policies
  4. Click Create Intrasite/Intersite Profile

    5. In the Create Intrasite/Intersite Profile:
  5. Click Submit
