Re: [ovirt-users] bonding mode-alb

Dear Luca, Sorry for the very late reply.. I want to try out now your mentions. Should I make an interconnect the two switches in active/backup mode? Thanks!

We're using it in almost all our setups and switches toin backup interface in 100ms when a link down is detected (Setting miimon=100). Doesn't aggregate bandwidth but is a very good solution for high availability whwn you can't configure lacp or a portchannel on switch side.
