Advanced Routing enables configuration of a Networking Hub's Transit Gateway route tables, as well as individual VPC subnet route tables.

Before You Begin

• Estimated time to complete: 5 minutes
• Ensure you are a member of the Admin role in your Stax tenancy

Create a Prefix List

Each Networking Hub and VPC can have as many prefix lists as required.

1. Log in to the Stax Console
2. Select Networks in the left-hand nav
3. On the Networks page, choose your desired Networking Hub
4. Click + Create, then select Prefix List. The Create a Prefix List form will be displayed
   

8. On the Create a Prefix List form, choose the prefix list type, either VPC or Hub
9. Complete the remainder of the fields:
   • Name: Enter a name for the prefix list
   • Max Entries: When selecting a value for Max Entries, consider how many entries you expect the prefix list to require, as it will consume this number of entries in attached route tables
   • Entries - CIDR Ranges: Enter each of the CIDR blocks that you wish to contain in this prefix list. The number of CIDR ranges entered must be fewer than or equal to the number specified in Max Entries
10. If creating a Hub prefix list:
    • Target type: Select the destination for routed traffic. Choose from a specific VPC, Direct Connect Gateway, VPN Connection, or a black hole
    • Target name: Choose the appropriate targets from the list
    
11. Click Continue to set the association rules
    • If you are creating a Hub prefix list, you must choose route table types, flat VPC zones, or a combination as appropriate
      
    • If you are creating a VPC prefix list, target the VPCs by selecting either specific VPCs, VPC types, or Flat VPC zones. Choose the subnet types that the prefix list should be associated to
12. Click Create to create the prefix list

The prefix list will be displayed on the Advanced Routing page once initialization has completed.
