    Group
  • The Juniper PE router providing MPLS Virtual Private Wire Service (VPWS) must be configured to have the appropriate virtual circuit identification (VC ID) for each attachment circuit.

    &lt;VulnDiscussion&gt;VPWS is an L2VPN technology that provides a virtual circuit between two PE routers to forward Layer 2 frames between two cust...

    Group
  • The Juniper PE router providing Virtual Private LAN Services (VPLS) must be configured to have all attachment circuits defined to the routing instance with the globally unique VPLS ID assigned for each customer VLAN.

    &lt;VulnDiscussion&gt;VPLS defines an architecture that delivers Ethernet multipoint services over an MPLS network. Customer Layer 2 frames are for...

    Group
  • The Juniper PE router providing Virtual Private LAN Services (VPLS) must be configured to have traffic storm control thresholds on CE-facing interfaces.

    &lt;VulnDiscussion&gt;A traffic storm occurs when packets flood a VPLS bridge, creating excessive traffic and degrading network performance. Traffi...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper PE router must be configured to implement Protocol Independent Multicast (PIM) snooping for each Virtual Private LAN Services (VPLS) bridge domain.

    &lt;VulnDiscussion&gt;PIM snooping provides a way to constrain multicast traffic at Layer 2. By monitoring PIM join and prune packets on each inter...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper PE router must be configured to block any traffic that is destined to IP core infrastructure.

    &lt;VulnDiscussion&gt;IP/MPLS networks providing VPN and transit services must provide, at the least, the same level of protection against denial-o...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper PE router must be configured with Unicast Reverse Path Forwarding (uRPF) loose mode enabled on all CE-facing interfaces.

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

  • SRG-NET-000205-RTR-000016

    <GroupDescription></GroupDescription>
    Group
  • The Juniper PE router must be configured to ignore or block all packets with any IP options.

    &lt;VulnDiscussion&gt;Packets with IP options are not fast switched and therefore must be punted to the router processor. Hackers who initiate deni...

    <GroupDescription></GroupDescription>
    Group
  • The Juniper PE router must be configured to enforce a Quality-of-Service (QoS) policy in accordance with the QoS GIG Technical Profile.

    &lt;VulnDiscussion&gt;Different applications have unique requirements and toleration levels for delay, jitter, bandwidth, packet loss, and availabi...
