<html><body><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12pt"><div>Hello,</div><div>I have a setup of virtual machines and wherein my virtual switch (OVS) takes care of switching locally and it uses the network for talking to VM's outside the server (like a VEB scenario I guess). I want Netlink messages to be sent to LLDPAD. I understand that i had to modify the XML files and start the VM. But, i see from the XML that it supports only VEPA, not VEB.<br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color: transparent; font-style: normal;">But, irrespective of VEB or VEPA, those VM information should be known to the upstream switch through VDP. 802.1QBG seem to support this (both VEPA and VEB)</div><div style="color: rgb(0, 0, 0); font-size: 16px;
