  • The Juniper perimeter router must be configured to drop fragmented IPv6 packets where the first fragment does not include the entire IPv6 header chain.

    &lt;VulnDiscussion&gt;One of the fragmentation weaknesses known in IPv6 is the "undetermined transport" packet, which is the first fragment where t...

    Group
  • The Juniper 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 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.
