How to config Host DPDK Port and Instance Port in ONE ovs-dpdk-bridge?

Solution In Progress - Updated -

Issue

  • In default installation with director.

a) The host DPDK Port "dpdk0" is linked in br-link0 ovs-dpdk-bridge.

    Bridge "br-link0"
        Port "dpdk0"
            Interface "dpdk0"
                type: dpdk

b) And the Instance Port "vhuxxx" is linked in br-int ovs-dpdk-bridge.

    Bridge br-int
        Port "vhucd4dc1ed-12"
            tag: 2
            Interface "vhucd4dc1ed-12"
                type: dpdkvhostuser

c) This two bridge is connected by patch peer.

    Bridge "br-link0"
        Port "phy-br-link0"
            Interface "phy-br-link0"
                type: patch
                options: {peer="int-br-link0"}
    Bridge br-int
        Port "int-br-link0"
            Interface "int-br-link0"
                type: patch
                options: {peer="phy-br-link0"}
  • This setup increases the number of hops for a network packet. Tried to club up the two OVS bridges into one using following change in template.
network-environment.yaml:
  NeutronBridgeMappings: 'dpdk0:br-int'

Deployment went successful with this change but it's still showing the patch-peer in output.

    Bridge br-int
        Port int-br-int
            Interface int-br-int
                type: patch
                options: {peer=phy-br-int}
        Port "dpdk0"
            Interface "dpdk0"
                type: dpdk
        Port phy-br-int
            Interface phy-br-int
                type: patch
                options: {peer=int-br-int}
