IPC integration of babeld with OpenWrt.
|
|
|
|
The ubus interface offers following functions:
|
|
- get_info
|
|
- get_neighbours
|
|
- get_xroutes
|
|
- get_routes
|
|
|
|
All output is divided into IPv4 and IPv6.
|
|
|
|
Ubus notifications are sent if we receive updates for
|
|
- xroutes
|
|
- routes
|
|
- neighbours
|
|
|
|
The format is:
|
|
- {route,xroute,neighbour}.add: Object was added
|
|
- {route,xroute,neighbour}.change: Object was changed
|
|
- {route,xroute,neighbour}.flush: Object was flushed
|
