[j-nsp] single ip on two interfaces
Is it possible to have the same ip accessible via two interfaces the same way you would on a server. This is on an mx series router.

Assigning the same IP address to separate interfaces (logical or physical) is usually wrong, unless each interface is in a separate routing instance/VRF. Can you describe your scenario?

I think Mark is referring to bonding under linux...right? Typically bonding has an active / passive pair, and it can also round robin sending the packets out individual interfaces. Obviously all returning traffic will be destined to one mac, which is the active slave at the time. Bonding also supports LACP though.

Re: [j-nsp] single ip on two interfaces
I'm making VC's out of all our existing 3300 top of rack switches, as well as the EX8200 core, resulting in no spanning tree bs, 40gbit lags + lacp to the tor vc and SRX cluster, plus 2-4gbit lags to the server using lacp bonding mode. It works great as long as layer 4 hashing is configured server side to allow for more than 1gbit between two hosts. Bonding isn't extremely robust by itself.

I know people have done it, i just cant personally speak from experience On Tue, Mar 5, 2013 at 7:23 PM, Morgan McLean wrx...@gmail.com wrote: I think Mark is referring to bonding under linux...right?
