Hi,
As I know you can not directly trigger to change the default route.
I don't know about batman-ex but batman allows that. Depending on your needs you have several options:
- If you know what gateway you want you can use the -p option even at runtime: batmand [-c] -p <IP>
- If you want that batman chooses a better gateway based on the TQ as soon as it is available use -r XX (also available at runtime) where XX bgreater than 3. To switch to a new gateway as soon as its TQ values is 20 points higher than the current gateway: batmand [-c] -r 20
