HW VTEP replication modes supported with ODL


Arunkumar R G
 

Hi,

With ODL as controller, what are the replication modes supported to handle BUM traffic??

Specifically whether head-end replication is supported i.e. HW-VTEP replicating it to all the VTEPs? If yes, how HW-VTEP can get to know the other VTEP info from OVSDB's vtep.db?

Thanks,
Arun.

odl currently only supports HER. 
all remote vteps are programmed by the controller in the mcast_mac_remote table for the keyword 'unknown_dst'. 
a schema update has been added to hwvtep schema recently to explicitly set the mode to either HER or service node.
We will plan on enabling the mode explicitly using this parameter for the Nitrogen cycle.

thanks,
daya

+suneel, vishal , please correct me if i am wrong..

Hi Arun,

I believe ovsdb hwvtep plugin don't do any explicit routing of the traffic, it's upto the application how it configure. Hwvtep can learn about all the other vteps by fetching the data from the ovsdb db.
