L3 Hub-and-Spoke VPN
Merging Hub and Spokes
For the existing hub-and-spoke VPNs, NorthStar Planner does not automatically group together the vrf associated with the hub and the vrf associated with the spoke. This should not affect routing, but for readability purposes, users can manually group together the hub and spoke into one VPN using the following procedures.
- Select Network > VPN, and identify the vrf’s to
combine. If you select the To Import/Export Relation View from the
VPN Topology tab, it will show you which other instances to combine
together.Figure 1: Spoke View
Figure 2: Import/Export Relation View (Spoke -> Hub)
Since some hub-and-spoke VPN’s can have an upstream and downstream spoke, it may be best to check the Import/Export Relation View of the hub.
- Select the hub-and-spoke components from the Summary > Layer 3 VPN list
on the right pane and use the Actions > Set Service menu to provide a name
for the hub-and-spoke VPN.Figure 3: Specifying the Hub and Spoke VPN via “Set Service”
- Select the newly defined service from the Services category
to view the VPN topology of the hub and spoke VPN.Figure 4: Hub and Spoke VPN Topology
- For the combined VPN, select Network > Protocols. To identify
the Hub PE node, right-click the table column header and select Table Options, and add the property “Hub” to the
“Selected Items” list on the right-hand side, to see the
Hub checkbox column.Figure 5: Hub Checkbox Column
Adding a New Layer 3 Hub-and-Spoke VPN
Configuring a L3 Hub-and-Spoke VPN is similar to configuring a regular L3 full-meshed VPN, except for the following additional steps.
First follow the steps outlined in previous section on L3 VPN configuration until you reach the Hub-and-Spoke configuration window. Click on the checkbox that says Configure Hub-and-Spoke MPLS VPN, and then move each PE to the appropriate list (Spoke Site Device(s) list or Hub Site Device(s) list) by using the Hub-> and <-Spoke buttons. The VPN Wizard automatically suggests RT exports and imports for both the hub sites and the spoke sites in order to establish a hub-and-spoke relationship. As before, you have the option to change the RT list by editing the suggested export or import values or by using RTs from the Route Targets table (by clicking on the magnifying glass icon).
Figure 6: Hub-and-spoke VPN configuration
Click on Next to get to the window where you would configure PE facing CE interfaces as described in the previous section on L3 VPN configuration. The following figure shows what the configuration looks like after the interfaces have been assigned. Notice that GI_C2 is configured as the hub site.
Figure 7: Assigning PE facing CE interfaces in the Hub-and-Spoke VPN
After configuring the PE-CE protocol details under the Details tab (as described in the previous section on L3 VPN configuration), the resultant L3 hub-and-spoke VPN is shown in the following figure. Notice that Import RT 17301:65016 is highlighted to indicate that it is only an import RT for the HuB site(s).
