Create static routes for given router as defined in input_dict

|

Parameters
|
||||
----------
|
||||
* `tgen` : Topogen object
|
||||
* `input_dict` : Input dict data, required when configuring from testcase
|
||||
* `build` : Only for initial setup phase this is set as True.
|
||||
|
||||
Usage
|
||||
-----
|
||||
input_dict should be in the format below:
|
||||
# static_routes: list of all routes
|
||||
# network: network address
|
||||
# no_of_ip: number of next-hop address that will be configured
|
||||
# admin_distance: admin distance for route/routes.
|
||||
# next_hop: starting next-hop address
|
||||
# tag: tag id for static routes
|
||||
# delete: True if config to be removed. Default False.
|
||||
|
||||
Example:
|
||||
"routers": {
|
||||
"r1": {
|
||||
"static_routes": [
|
||||
{
|
||||
"network": "100.0.20.1/32",
