How to add and delete route entries for a network instance - Cloud Enterprise Network

After connecting a Virtual Border Router (VBR) or Virtual Private Cloud (VPC) to an Enterprise Edition transit router, you can add custom route entries for the network instance if route synchronization is disabled. The next hop defaults to the VBR or VPC connection. Added entries propagate automatically to the instance route table, directing traffic into the transit router.

Limitations

Enterprise Edition transit routers support adding route entries only for VBRs and VPCs—not for IPsec-VPN connections or Express Connect Router (ECR) instances. Each added entry automatically propagates to the VBR or VPC route table and counts against your custom route entry quota.

Add a route entry

Make sure the transit router instance version is Enterprise Edition.

Log on to the CEN console.
On the CEN Instance page, click the ID of the CEN instance that you want to manage.
Go to the Basic Information > Transit Router tab and click the ID of the transit router that you want to manage.
On the details page of the transit router, click the Network Instance Route Table tab, select the target network instance and route table, and then click Add Route Entry.

In the Add Route Entry dialog box, configure the route entry and click OK.

Parameter	Description
Network instance ID	ID of the network instance for the new route entry.
Route table ID	ID of the target route table.
Destination CIDR	Destination CIDR block. Example: 192.168.10.0/24.
Next Hop	Read-only. Displays the current transit router ID. The actual next hop is the connection to the selected network instance.

Delete a route entry

You can delete only route entries where the Type is listed as Transit Router Connection.

Log on to the CEN console.
On the CEN Instance page, click the ID of the CEN instance that you want to manage.
Go to the Basic Information > Transit Router tab and click the ID of the transit router that you want to manage.
On the details page of the transit router, click the Network Instance Route Table tab.
