QuestionQ29

Prepare and present the solution

You have designed a two-tier L2 data center network for a customer. While presenting the solution, the customer states that they have a mission-critical multicast application with sources and receivers in the data center.

Which CX feature, in addition to features supplied by the PIM-SM standard, should you explain to emphasize the value of your solution?

  • A PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails
  • B VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
  • C Fast switchover from the RP tree to the shortest path tree
  • D Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures
Explanation

Aruba CX PIM-SM Active-Active with VSX synchronizes multicast forwarding state across the VSX peers. One peer operates as the designated router and the other as the proxy DR; because the proxy has the multicast tree state prepared, it can assume forwarding rapidly after the DR peer fails, minimizing multicast-stream interruption.
