Network Design

Company XYZ plans to redesign the Layer 2 portion of its network and wants to use every available uplink to improve performance. It also requires end-host reachability that supports conversational learning. However, because of design constraints, it cannot deploy port-channels on the uplinks. Which alternative technique can ensure the uplinks operate in an active/active state?

  • A TRILL
  • B LISP
  • C MSTP
  • D switch stack
Explanation

TRILL provides loop-free Layer 2 shortest-path forwarding and equal-cost multipath across redundant links, allowing multiple uplinks to forward actively without a port-channel. It distributes end-station reachability through the TRILL fabric while avoiding the blocked-link behavior of spanning-tree topologies.
