Hi Everyone,

I have setup Openstack Juno environment by referring to the following link with 1 controller, computer & network node.

Everything seems to be working fine but from the neutron config i have followed from the above link i have setup FLAT network due to which i only have access to one FLOATING IP subnet.

I would like to setup trunk link so i can utlize external link for multiple VLAN's.I have already configured cisco switch as a trunk but I am not sure how to configure network node external interface as trunk. Can someone help me with this configuration please? Thanks!

you will need to use provider type VLAN for the external network, and the l3_agent.ini will need the external network bridge set to a blank string, i.e. external_network_bridge=

This example uses FLAT, but VLAN would be very similiar
