That's for bridging a trunk, but what about bridging between vlans: vconfig add eth0 5 vconfig add eth0 6 brctl add br0 eth0.5 brctl add br0 eth0.6 While you could combine the vlans, doing this allows you to force all traffic through packet filtering/traffic shaping/IDS. Usually you wouldn't then see the same MAC on two different VLAN but you might on spanning tree packets. _______________________________________________ Bridge mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/bridge
