Refer to the exhibit. The users establish a tunnel between branch A and B to communicate directly during video calls. The tunnel must go down after the call is complete. Which two configurations…

`omp send-path-limit 16` controls the number of TLOC paths advertised for vRoutes to the vSmart controller, which is not related to on-demand tunnel behavior.

The `system on-demand enable` command activates the on-demand tunnel feature on spoke devices, allowing them to dynamically establish direct data plane tunnels for traffic like video calls.

`vpn 0 service TE` configures traffic engineering within VPN 0, which is distinct from the dynamic on-demand tunnel establishment and teardown requirement.

The `system on-demand idle-timeout 10` command configures these dynamically created on-demand tunnels to tear down after 10 minutes of inactivity, ensuring the tunnel closes once the video call concludes and no further traffic is sent.

`omp ecmp-limit 16` sets the maximum number of equal-cost paths for traffic forwarding, not the parameters for on-demand tunnel creation or expiry.
