Subject: [B.A.T.M.A.N.] multicast packet loss
Date: Mon, 06 Aug 2012 15:05:49 +0200 [thread overview]
Message-ID: <501FC12D.3040608@gmail.com> (raw)
Hi all!
I am experiencing a multicast packet loss on batman-adv mesh, this can
appear normal but it is not because the mesh is on top of wired Ethernet
link!
the host fe80::c8e0:2cff:fe9b:6d1f is sending a multicast hello message
every 4 seconds on bat0 interface, but as you can see from the dump
timing on a machine attached on the same switch they are not arriving
regurarly so what is happening? Is this normal?
here is the dump
eigenServer ~ # tcpdump -n -i bat0 udp port 6696 and host
fe80::c8e0:2cff:fe9b:6d1f [4/323]
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on bat0, link-type EN10MB (Ethernet), capture size 96 bytes

batman version is the same on both host
eigenServer ~ # batctl -v
batctl gentoo-2012.2.0 [batman-adv: 2012.2.0]
thanks for help!
