Route Overview
What Is a Route?
Routes are used to forward packets. A route contains information such as the destination, next hop, and route type.
You can create a propagation for attachments to automatically propagate routes to route tables or manually add static routes to route tables.

Propagated routes |
Propagated routes are routes that attachments propagate to the route tables of the enterprise router. They cannot be modified or deleted. |
To create a propagation, see Creating a Propagation for an Attachment in the Route Table. |
Routes are classified into propagated routes and static routes. The routes shown in Figure 1 are described as follows:
|
Static routes |
Static routes are manually created and can be modified or deleted. |
To create a route, see Creating a Static Route. |
Route Priority
If there are multiple routes with the same destination but different targets in a route table, the route priority is as follows:
Static route > propagated route for attachment > propagated route for virtual gateway attachment > propagated route for VPN gateway attachment

- Static routes are manually configured and the destination of each static route must be unique in a route table.
- Propagated routes are automatically learned by the system and may have the same destination in a route table.
- A static route and a propagated route may have the same destination in a route table.
