This is what i have configured on my compute node. I have two NIC and both nic connected to same cisco switch but [eth1] is trunk port.
[eth0] - Management (vlan30) [eth1] - (br-vlan bridge) - Data traffic (vlan 30,10) - Trunk to cisco Do you think this is creating loop? how do i solve this issue then? vlan30 is private address pool (10.x.x.x) but sometime i need instance running on vlan30 (10.x.x.x) pool too that is why i added vlan30 [eth1] On Tue, Sep 20, 2016 at 8:52 AM, CARVER, PAUL <[email protected]> wrote: > > Satish Patel [mailto:[email protected]] wrote: > >>How do I stop that loop at ovs?
