This is the normal behavior of any bridge/switch. - If the bridge learned this MAC address, it will forward the packet to this port only. - If the bridge didn't learned this MAC address, it forward the packet to all ports. To display the currently learned MAC address and associated port, use brctl showmacs <bridge_name> Nicolas. > >> >> On Wed, Feb 2, 2011 at 6:04 AM, Sinbad<sinbad.sinbad@xxxxxxxxx> wrote: >>> hi, >>> >>> suppose my config is as below. >>> >>> # brctl addbr mybridge >>> # brctl addif mybridge eth0 >>> # brctl addif mybridge eth1 >>> # ifconfig mybridge up >>> # ifconfig mybridge 192.168.100.5 netmask 255.255.255.0 >>> >>> now if the an l3 packet has to egress from mybridge >>> which port will be chosen ? >>> >>> thanks >>> >>> >>> On Wed, Feb 2, 2011 at 1:53 PM, Nicolas de PesloÃan >>> <nicolas.2p.debian@xxxxxxx> wrote: >>>> >>>> Le 02/02/2011 09:02, Sinbad a Ãcrit : >>>>> >>>>> hi, >>>>> >>>>> suppose a vlan has 3 member ports and vlan is configured as an l3 >>>>> interface >>>>> and if data is suppose to go out using that vlan interface, which >>>>> physical port >>>>> will be chosen among the 3 member ports ? >>>> >>>> Can you describe your configuration a little bit more (possibly using the >>>> commands used to setup that configuration)? >>>> >>>> Nicolas. >>> >>> >>> _______________________________________________ >>> Bridge mailing list >>> Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx >>> https://lists.linux-foundation.org/mailman/listinfo/bridge >>> >> > _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
