My customer is upgrading their network infrastructure, VLAN configs and policies. They are looking for some guidance around updating the BGP key for their existing Direct Connect infrastructure at AWS side. What's the best practice / recommended solution.

Currently, it is not possible to directly edit the BGP keys once the interface is created. To modify the key on a VIF there are two options:
-
Create a new VIF.
- If similar parameters is required, delete the old VIF and create a new one with similar desired parameters as the VLAN on the VIF has to be unique. Otherwise:
- If possible, assign a new VLAN and create a new VIF (this requires creating a new VLAN interface on your on-premises router).
- Establish BGP on the new VIF.
- Test the connection thoroughly.
- Once confirmed working, delete the old VIF.
-
Recreate the BGP Peering. Under the existing virtual interface:
- Add a new peering for IPv6.
- Delete the existing IPv4 peering.
- Create a new IPv4 peering with the new BGP key.
- Remove the temporary IPv6 peering.
