This option provides another way to attach to a specific bridge that is not quite equivalent with how bridge_mappings work in the L2 agent. This creates inconsistencies between how the L3 agent behaves when configured with a bridge_mapping and provider properties of the Neutron network vs. when it just ignores all L2 stuff and plugs itself directly into the bridge. See the bug report for more info. Change-Id: I37de3cd6eaaf34856fa72753f471f4f0a9381836 Closes-Bug: #1491668
