BGP Route Injection Scenarios
|

|
|
|

Each scenario is a dict with:
|
||
|
|
description: str
|
||
|
|
routes: list of route dicts
|
||
|
|
|
||
|
|
Route dict keys:
|
||
|
|
prefix (required) e.g. "1.1.1.0/24"
|
||
|
|
next_hop default "self"
|
||
|
|
as_path list of ASNs, e.g. [65100, 1299, 15169]
|
||
|
|
communities list of strings, e.g. ["65100:100"]
|
||
|
|
med int, optional

local_pref int, optional
