Change your BGP Router IP
To change the IP address of your BGP router:
- Go to ISP Portal asset page.
- Select GGC node name > Configuration tab.
- Click "Update Configuration" in the "Node Configuration" section.
- A new "Node Change" ticket will open.
- Change the BGP Router IP address, then click "Update" .
Our systems will take several hours to update the configuration. We will email you when the update is complete.
If we can’t connect to the BGP router, we'll contact you for help.
While the BGP session is down, the node continues to operate using cached prefixes.
Change your GGC node Subnet
To change the entire IPv4 or IPv6 subnet allocated to of a GGC node, contact ggc@google.com. This change requires coordinated updates on both sides.
Enable IPv6
To enable IPv6 traffic on an existing GGC node:
- Visit the ISP Portal asset page.
- Select GGC node name > Configuration tab.
- Click "Update Configuration" in the "Node Configuration" section.
- A new "Node Change" ticket opens.
- In the "IPv6 Details" section, select "Enabled" in the "IPv6" drop-down.
- Add the IPV6 Subnet (must be a /64) and your IPv6 BGP Router in the "Subnet" box.
- Click "Update".
- Configure your BGP router to announce at least 1 IPv6 prefix to the GGC node.
If we can't connect to the IPv6 network, we’ll contact you for help.
We make use of either static routes or Router Advertisements to configure the default IPv6 gateway on the GGC machines:
- If you prefer we use a separate gateway as advertised via Router Advertisements, ensure these are enabled and working properly.
- Otherwise, GGC machines will use the (:1) address from the IPv6 subnet as the default gateway.
Ensure that the GGC IPv6 subnet is globally advertised and accessible. It's common for us to detect major IPv6 routing issues for networks with working IPv4.
