[ovs-discuss] Tunnel path MTU discovery deprecated in 1.9 and what't the substitution?

2013-03-07 Thread Yeming Zhao
I saw the tunnel path mtu discovery featured deprecated and will be removed soon. This feature is quite handy for me actually. I'm wondering what's the work around after its removal, assuming I cannot go and manually change all the mtu values on the hosts. Thanks, Bryan __

[ovs-discuss] Can current newest OVS version support STT?

Hi! all, Can current newer OVS version support STT, or any STT patch? Since I want to do a overhead test about GRE, VXLAN, STT, etc as http://networkheresy.com/2012/06/08/the-overhead-of-software-tunneling/ did. From the maillist I have learned the newest version of OVS support VX

Hello! I was trying to bit-twiddle ARP packets with NXAST_REG_MOVE actions, when I found that NXM_OF_ARP_OP fields aren't writable. nicira-ext.h doesn't explicitly call out unacceptable destinations, although NXM_OF_ARP_OP isn't included on the list of acceptable dst. I am curious: 1) Is there a

Hi, Thank you! I'm studying the source code, but I'm getting a bit lost... In ofproto-dpif.c there are stat_update functions and some comments pointing to dpif_flow_get(), but I can't seem to find how the stats are exactly transferred between datapath and the corresponding (sub)facets in userspac

Hi, I'm using ovs with openflow and have noticed that flow stats seem to update about every second. So first question: Is this correct? Is it possible to have it update more often? (command line arg, or does it have to be changed in the source) I suppose this will imply heavier load (more commun

How controller can aggregate the networks efficiently by avoiding black hole for example we have following prefixes 10.0.0.0/24 10.0.1.0/24 10.0.2.0/24 10.0.7.0/24 if controller sends summary as 10.0.0.0/21 it will include extra network that we don't have in table like 10.0.3.0/24, 10.0.4.0/2
