Broadcast issue with bridge-domain on ASR9000

By default, Flood Optimization feature on ASR9K prevents broadcast and multicast frames to be flooded to the other interfaces that are located on different line cards.

For example, if one bridge-domain contains one Bundle-Ethernet interface and one physical interface Gigabit 0/1/0/12, broadcast received from interface G0/1/0/12 will never be flooded to the BE interface.

In some application, that's not a good idea. To change this, enter flood mode convergence-optimized command under bridge-domain configuration.
