Thank you for the direct link, looking forward to the summit talks to 
show up on youtube :)

Will there be documentation / guides on how to configure host traffic 
termination?

Yes we are looking at high bandwidth use cases (>10Gbps).
Since frr (bgp)/grout is expected to decide where to route the traffic 
(which grout interface), this can't be done using a separate non-grout 
interface on the same system, correct? So we would use the TUN/TAP setup 
I guess or am I missing something? :)
