Cisco IOS XR Router RTR Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Cisco PE router must be configured with Unicast Reverse Path Forwarding (uRPF) loose mode enabled on all CE-facing interfaces.

    <VulnDiscussion>The uRPF feature is a defense against spoofing and denial-of-service (DoS) attacks by verifying if the source address of any ...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
