Hello,
My setup : CS 4.1 (snapshot 2013/04/11)
Advanced network, 3 physical networks (public, guest, mngt/storage)
Guest network interfaces are connected on a switch L2, with trunk
enabled on vlan tagged 200-300 (and 199 for untagged packets)
Works fine:
Node 1 : VM + Virtual Router
Node 2 : nothing
I can ping VM since VR (on private network),
I can ping VR since VM (on private network),
I can ping VM on public IP.
Works with >80% ping loses
Node 1 : Virtual Router
Node 2 : VM
I can ping VM since VR (on private network) with alot of lost packets,
I can ping VR since VM (on private network) with a lot of lost packets,
I can ping VM on public IP with a lot of lost packets.
On VM, when I make some "arp -n" concurrent with ping VR, I found that
the arp address of VR changes!
ARP address 1 matches with p5p1 / p5p2 / bond2 / guestbr2 (on Node 1)
(note I use IP Bonding, but currently p5p2 isn't cable connected)
ARP address 2 matches with vnet4 (on Node 1)
(note this address is the mac address of VR/eth0)
Can you help me? this is a bug or misconfiguration?
Need add some kernel parameters on hosts related with arp?
Thanks.
Milamber
