Folks,
I really struggle to get 802.1q trunks with VLANS working with openvswitch.
The server that got issues is a VXLAN GW on an ESX machine. That server should
create connectivity for the VM's on ESX to the domains in KVM.
The VXLAN-GW machine has two interfaces:
eth0: native untagged for mgmt connectivity
eth1: 802.1q tagged for all user VLAN's
eth0 is up and forwards traffic as intended.
eth1 can talk to IP' addresses via vlans if there is no OVS involved. eth1.1,
eth1.100, eth1.101 work fine if directly addressed.
I have tried now over three days dozens of configuration but can't get these
scenario up and running correctly.
I would like to connect VLAN 1, 100 and 101 to the local VXLAN GW and also
tunnel these VLANs over VXLAN to the KVM host. (Tunnel works fine)
Strange is that I do see the ARP reply, but no L3 connectivity goes trough.
I have tried "normal" ovs-vsctl based configuration and also ovs-stanza
configuration. I have pasted below the OVS-Stanza config as I think that is
most clean.
Any tip please ?
ovs-vsctl show
