Re: [zones-discuss] Bridging at Zones.
Wow! That is just perfect James... I'm pretty sure I'll use all this information for the simulation... About the "Appointed Forwarder operation or DR election" I will need to simulate those too... for that, as you suggested, I'll use two computers with 4 Ethernet link. Thanks a lot! Best Regards.

Re: [zones-discuss] Bridging at Zones.
James, Thank you for you answer. I had never though about running more than one instance of Trill on the same machine... simnet links are new to me... a quick search on Google didn't give me much. Do you have any links about it? There is no problem in running this simulation on the global zone... but the objective is to simulate a regular network running only regular bridges and then I would substitute bridges for Trill links (one by one). Can you see any problem doing that without virtualization? Thanks for your help I really appreciate. Regards Daniel.

I wouldn't expect that to work well in a zone. For one thing, the TRILL forwarding table isn't zone-aware. If you need to run multiple instances of TRILL on a single system, you can do that. The design supports having multiple instances of TRILL, and (using simnet links) can simulate complex networks. See: http://mail.opensolaris.org/pipermail/rbridges-dev/2009-June/000576.html Because it's a bridging solution, and bridging takes place logically below the layers that do VLANs and VNICs and the like, it uses physical interfaces. If you really need to keep it out of the global zone for some reason, I think you'll need to run it in a VM. But I don't understand the scenario in which that would be required. -- James Carlson 42.703N 71.076W ___ zones-discuss mailing list zones-discuss@opensolaris.org

No problem Edward, thank you for trying to help. If there is any group or person that you can indicate me so I can talk about theses issues, it would be great.

Re: [zones-discuss] Bridging at Zones.
Hi Edward, I believe i was not so clear about the problem. I'm not trying to create vnics from inside the zone... I'm trying to run this command inside the container: "dladm create-bridge -P trill -l net0 mytrillBridge" (net0 being the vnic create from global zone). Like I said, Trilld have a requisite that in order to run, a bridge in Trill protect mode must be initiated, but the command above output that I cannot create a bridge since net0 is a vnic. Eric suggest: "You may need to delegate physical NICs to the container..." and I believe that virtualizing Solaris from a Vmware ou Xen Hypervisor, giving a lot of "vmware network cards" should be enough... If you or anybody else on the list have another idea of how to run trilld from inside a Container I would love to know. Thank you for your interest and time. Regards.

Re: [zones-discuss] Bridging at Zones.
you can't create vnics from inside a zone. (it's not supported.) but the global zone can create additional vnics and give them to the zone. the easiest way to do this is to have the global zone administrator update the zonecfg for you zone to include multiple "anet" resources, one for each vnic that you want. when they create an "anet" resource they can specify the physical link that the vnic should be created on top of (via the anet lower-link property). ed On Tue, Aug 21, 2012 at 02:58:04PM -0300, Daniel Requena wrote: > Hello, > >I'm trying to run a simulation for my master thesis using Solaris > Containers, but I'm having a problem. >I need to run Trilld inside the containers, but in order to run trilld I > must be able to Bridge network cards... when I try to run dladm to create > the bridge inside a container, it says that a vnic cannot be bridged... :/ >The main objective in this simulation is to emulate a trill switch cloud > all interconnected but this "bridge" problem is killing me.. >Is there a way to use a different nic inside the containers so I can run > trilld? >Any help or idea is appreciated. > > Regards. > Daniel. > ___ > zones-discuss mailing list > zones-discuss@opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

[zones-discuss] Bridging at Zones.
Hello, I'm trying to run a simulation for my master thesis using Solaris Containers, but I'm having a problem. I need to run Trilld inside the containers, but in order to run trilld I must be able to Bridge network cards... when I try to run dladm to create the bridge inside a container, it says that a vnic cannot be bridged... :/ The main objective in this simulation is to emulate a trill switch cloud all interconnected but this "bridge" problem is killing me.. Is there a way to use a different nic inside the containers so I can run trilld? Any help or idea is appreciated. Regards. Daniel. ___ zones-discuss mailing list zones-discuss@opensolaris.org
