Cisco IOS XE Switch RTR Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The MPLS switch with RSVP-TE enabled must be configured with message pacing to adjust maximum burst and maximum number of RSVP messages to an output queue based on the link speed and input queue size of adjacent core switches.

    <VulnDiscussion>RSVP-TE can be used to perform constraint-based routing when building LSP tunnels within the network core that will support Q...
