Hi Ivan,
you are doing an amazing job here. I have one question/feedback about one of quiz questions:

i doubt if "Only one session is established between the System-IP addresses" is correct statement. in cisco web site, it says "By default, each tunnel interface in VPN 0 can establish two control connections."
number of control connections per vedge and per-tunnel interface (tloc) is apparently configurable. pls refer to link below

Hello nthere_krn,

It is the vEdge router as a whole, not the individual tunnel interfaces in VPN 0, that establishes an OMP session with vSmart. When there are multiple DTLS control connections on the router to the same vSmart controller, the vEdge router creates a single OMP session and the different tunnel interfaces use this single OMP session. This can be easily verified using the show control connections and show omp peers commands on a vEdge.

However, there might be multiple OMP sessions in designs with multiple data centers having multiple vSmart controllers grouped with different controller identifiers and vEdge affinity.

That is my understanding, hope it helps,
Ivan Ivanov
