This document describes how you can modify VLAN attachments for Partner Interconnect.
The following table lists properties associated with VLAN attachments and describes what to do if you want to modify a property:
|Property||How to modify|
|Capacity||To modify capacity, you must work with your service provider as described in the Modifying capacity section of this document.|
|Description||See the instructions in this document for Modifying the description. Modifications are immediate and don't disrupt traffic.|
|Whether a VLAN attachment is enabled or disabled||To disable or re-enable a VLAN attachment, see Disabling VLAN Attachments.|
|VLAN ID||You can't modify these properties for existing attachments. Instead, you must recreate the VLAN attachment. To create VLAN attachments for Partner Interconnect, see Creating VLAN attachments.|
|BGP IP addresses (Cloud Router IP, on-premises router IP)|
The peer ASN is not a property of the VLAN attachment— it is part of the
BGP configuration of the
Cloud Router. If you
have a Layer 2 connection and you want to modify
the peer ASN, update the Cloud Router's BGP session for the VLAN
attachment. For more information, see
Viewing Cloud Router configuration,
glcoud compute routers update-bgp-peer command reference,
routers.update API method reference.
For an existing VLAN attachment, Google Cloud supports increasing or decreasing the attachment's capacity as your capacity demands rise or fall. Because capacity changes can affect your service provider's network, you must work with them to change your attachment's capacity. Changes in capacity, in rare cases, can cause traffic disruption. If traffic is disrupted, the disruption lasts less than a minute.
After the service provider has updated your attachment, your service provider works with Google to update the attachment's capacity in your GCP project. At that time, Google updates the charges for the attachment based on the new capacity.
For a list of all the supported service providers, see Service Providers.
