Modifying a Static Route
|
|
========================
|
|
|
|
Scenarios
|
|
---------
|
|
|
|
This section describes how to modify static routes, including common routes and blackhole routes, in a route table of an enterprise router. For example, you can perform the following operations:
|
|
|
|
- Change a common route to a blackhole route.
|
|
- Change the attachment type and next hop of a common route.
|
|
|
|
Only static routes can be modified. Propagation routes cannot be modified.
|
|
|
|
Notes and Constraints

To change the destination of a static route, delete this static route and create another one with your desired destination.
