In this topology, two CX 8325 switches form a VSX stack using the active gateway. What is the nature and behavior of the Virtual IP for the VSX pair when clients connect to the access switch and use VSX as their default gateway?

  • A Virtual floating IP will failover in case of a failure
  • B Virtual IP is active on both CX switches
  • C Virtual IP uses SVI IP address synced with VSX
  • D Virtual IP is active on the primary VSX switch
Explanation

A VSX active gateway is an active-active default gateway: both VSX peers use the same virtual gateway IP and virtual MAC address and can forward client traffic. The active-gateway configuration must be consistent across the two VSX switches; it is not a primary-only or floating failover gateway.
