  • The Cisco BGP router must be configured to reject route advertisements from CE routers with an originating AS in the AS_PATH attribute that does not belong to that customer.

    &lt;VulnDiscussion&gt;Verifying the path a route has traversed will ensure that the local AS is not used as a transit network for unauthorized traf...

  • The Cisco BGP router must be configured to use the maximum prefixes feature to protect against route table flooding and prefix de-aggregation attacks.

    &lt;VulnDiscussion&gt;The effects of prefix de-aggregation can degrade router performance due to the size of routing tables and also result in blac...

  • The Cisco MPLS router must be configured to synchronize IGP and LDP to minimize packet loss when an IGP adjacency is established prior to LDP peers completing label exchange.

    &lt;VulnDiscussion&gt;Packet loss can occur when an IGP adjacency is established and the router begins forwarding packets using the new adjacency b...

  • The MPLS router 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 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.
