Just happened that I asked the same 9 days ago: http://lists.linux-foundation.org/pipermail/bridge/2007-April/001764.html Depending on the switch on the other side of the wire, you will get the arp packets you send out on the other link of the bond. This will make an outgoing arp packet register on the internal port of the bridge and reregister a couple of ms later on the outer port. This leads to packets loss of > 99%, e.g. a 2x1GB bond degarded to 70kB/sec. It would be nice if the bridging code could prevent this. Either by identifying the outgoing arp packet that immediately returns and not updating the forwarding database, or allowing to hardcode some static arp entries into the forwarding database. --=20 Axel.Thimm at ATrpms.net --GPJrCs/72TxItFYR Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFGI/tCQBVS1GOamfERAgnxAJsF3wCnbVxTbyX/YiicfxPFQnBSMwCfYuWr TAb0X0frvO+yeRmym2yP9/4= =3Uvm -----END PGP SIGNATURE----- --GPJrCs/72TxItFYR--
