Question
How does the replicator role function in cisco SD-WAN?
Options
- AWAN Edge devices advertise the rendezvous point to all the receivers through the underlay network.
- BvSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.
- CWAN Edge devices advertise the rendezvous point to all receivers through the overlay network.
- DvSmart Controllers advertise the rendezvous point to all the receivers through the underlay network.
Explanation
The replicator role in Cisco SD-WAN, handled by vSmart controllers, advertises rendezvous points to receivers over the overlay network to facilitate multicast data plane operations.
Common mistakes.
- A. WAN Edge devices are not responsible for advertising rendezvous points in the replicator role; that is a control plane function handled by vSmart controllers.
- C. WAN Edge devices do not advertise rendezvous points as part of the replicator role; this is a vSmart controller function.
- D. vSmart controllers advertise rendezvous points over the overlay network using OMP, not the underlay network, to ensure secure and controlled distribution of multicast routing information.
