DVR Backbone
The DVR Backbone is a dedicated point-multipoint IS-IS control plane I-SID based signalling tree that
allows all DVR controllers belonging to different DVR domains to communicate DVR host IP routes. This
allows DVR controllers, for their L2 VSN interfaces configured for DVR, to have full visibility of all host IP
routes for the L2 VSN segment including host routes which are located in different DVR domains.
It is also possible to let campus L3 BEBs join the same DVR Backbone to get control plane visibility of all
available data center host routes. In some architectures with dual data centers where each data center uses
separate DVR domains, it is possible to create a redistribution policy on the campus BEB to install selected
DVR host routes into the BEB data plane IP routing table in order to solve north-south traffic tromboning
problems.
Zero Touch Fabric (ZTF)
Zero Touch Fabric is the ability to deploy a new switch in an existing SPB fabric and for that switch to
automatically derive the necessary SPB parameters, such IS-IS area and SPBM nickname, directly from the
already operating fabric network.
Tip
Zero Touch Fabric is supported on Extreme VSP platforms.
