Thanks, Toshiaki.

What is the right way to set the default_pvid using the bridge command
? I tried this, which fails..

root@...-3:~# ip link set dev vxlan0 name untagged type vlan id 0
RTNETLINK answers: Operation not supported
root@...-3:~#

All the interfaces in the bridge are untagged.

thanks,
Manohar.
