  • The multicast Rendezvous Point (RP) Arista router must be configured to filter Protocol Independent Multicast (PIM) Register and Join messages received from the Designated Router (DR) for any undesirable multicast groups and sources.

    &lt;VulnDiscussion&gt;Real-time multicast traffic can entail multiple large flows of data. An attacker can flood a network segment with multicast p...

  • The Arista router must be configured to produce audit records containing information to establish where the events occurred.

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

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

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.
