My environment is Centos6.4 with OpenStack Havana and vlan network. It runs correctly when I use L2 switch of Intel which doesn't support vlan tag. But when I change the switch to Cisco3560 which is L3 and can support vlan tag, it doesn't work at first. I also set all the interfaces in the switch to trunk and the vlan range is 2-1001.

But strange thing happened, when I set a switch interface to access, and assign it the vlan id that is the tenant external vlan id(not internal), the network works now.

I am totally confused. who can explain it and give me a solution?

Best wishes
