We noticed a few, unusual things: -> regardless of the link tested (kif or fastd3) and regardless of the node (node1, node2) small interruptions (loss-peaks) are appearing. -> These peaks appear almost synchronous, a few "noise" comes from different vpn-links and node-wan-uplinks. -> Since all links are wired, radio-noise won't have an impact -> The losses appear in batman-adv 2011.2.0 as well as in batman-adv 2012.4.0. Thus I suspect that batman-adv is triggering theses interruptions.
If you believe batman-adv is the culprit, please remove batman-adv from your test setup and repeat the exact same test. Otherwise we move into the realm of speculation.
Well, I started echoing on the underlying VPN-connection as well and changed the chart-titles for clearance:
In chart 4 and chart 5 RTT / Loss from kif.kbu to node-1 is measured. In chart 4 kif is sending ICMPv6 to the link-local address of bat0-interface - in chart 5 the link_local address of the underlying vpn-interface is used.
The loss-peaks appear in char 4 (bat0) only.
Thanks for your help,

Well, I set it f2up this list, since you're node subscribed. Sorry for not mentioning it.
