Network Design

Company XYZ branch offices connect to the headquarters sites through two links: MPLS and Internet. The company wants to design traffic flow so that voice traffic traverses the MPLS link, while all other traffic uses either the MPLS link or the Internet link. Which technique can the company use in its design to ensure that traffic is not process-switched?

  • A policy-based routing
  • B floating static route
  • C virtual links
  • D virtualization
Explanation

Policy-based routing classifies traffic, such as voice, and applies a route-map action to forward it to a specified MPLS next hop. Traffic that does not match the policy uses ordinary routing, allowing either available link according to the routing design. Cisco documents support for fast/CEF forwarding of packets forwarded through policy-based routing, which avoids process switching.
