Why would you stop locally generated traffic ? If say you have RIP, you can
stop it with the "passive-interface" command. What I mean is you have
absolute control of your router ...

Hi,

Is local PBR the only way to stop locally generated traffic?

Are there any other ways of doing this?

Thanks
Rohan

Outbounds access-list in not applied to locally generated traffic, it will
work for traffic transiting the router though.

If you want to stop locally generated traffic then look into doing local
PBR.
