    Configuring Forwarding

    With Contrail 1.03, the default forwarding mode is enabled for fallback bridging (IP FIB and MAC FIB). The mode can be changed, either through the Contrail web UI or by using python provisioning commands.

    From the Contrail web UI, select the virtual network for which you will change the forwarding mode, select Edit Network, then select Advanced Options to change the forwarding mode. In the following, the network named vn is being edited. Under Advanced Options->Forwarding Mode, two options are available:

    • Select L2 and L3 to enable IP and MAC FIB (fallback bridging).
    • Select L2 to enable only MAC FIB.

    Alternatively, you can use the following python provisioning command to change the forwarding mode:

    python provisioning_forwarding_mode --project_fq_name 'defaultdomain: admin' --vn_name vn1 --forwarding_mode < l2_l3| l2 >


    l2_l3 = Enable IP FIB and MAC FIB (fallback bridging)

    l2 = Enable MAC FIB only (Layer 2 only)
