dhcp reply lost between int-br1 and br-int
Hi, first of all, here my configuration: O.S. CentOS 6.4 x86_64 (SELinux disabled) Grizzly from RDO repos; Quantum with ovs plugin and vlan (3 vlan id configured at switch level, from 3501 to 3503); cloudctrl01 acts as keystone, glance, quantum-, rabbitmq, mysql, nova- (except network and compute); three interfaces: eth0 - management; eth1 - data; eth2 external; nova01 acts as nova-compute; two interfaces: eth0 - management, eth1 - data.
As far i understand, the path in the compute node should be: vm:demo01:eth0 <---> tapafa41705-77 <---> qbrafa41705-77 <---> qvbafa41705-77 <---> qvoafa41705-77 <---> br-int <---> int-br1 <---> phy-br1 <---> br1 <---> eth1
I suppose there something wrong on the compute node (nova01): with tcpdump i saw that dhcp reply arrive at int-br1 but not at br-int.
