Hello,
I''m having some dificulties troubleshooting a rather strange setup.
We have a Linux box, that is supposed to act as a shaper. For this,
there are several 802.1q vlans transported to one of the interfaces.
So the setup is something like this:
-------------------
- Cisco Router -
-------------------
/-------/ \-----------\
upstream | | client vlans
connection | |
\--- Gi1 - Linux Box - Gi2 ---/
Gi1 is an upstream connection, Gi2 holds several 802.1q vlans.
This already works with one vlan transported to it. However, when i try
to add another vlan and i try to send icmp packets from one side to the
other, arp relationships are established, however only _some_ of the
packets sent get a reply from the other side. Of course, testing was
done with all qdiscs removed.
STP is disabled on the bridge, so is rp_filter.
Does anybody have any idea what''s going on? Just keep in mind that
there
already is a connection that works without problems on the same machine.
