Can it?
It was years since I used Quagga though I don't
believe much has changed... it's still control
plane software. If there are ways to control ACLs
it's just that - control.
It's still the underlying OS, the kernel, which
handles packet forwarding and thus also packet
filtering with the ACLs that Quagga has defined.
