Juniper EX Series Switches Router Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • 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.

    <VulnDiscussion>Packet loss can occur when an IGP adjacency is established and the router begins forwarding packets using the new adjacency b...

  • The Juniper MPLS router must be configured to have TTL Propagation disabled.

    &lt;VulnDiscussion&gt;The head end of the label-switched path (LSP), the label edge router (LER) will decrement the IP packet's time-to-live (TTL) ...

  • The Juniper PE router must be configured to have each Virtual Routing and Forwarding (VRF) instance bound to the appropriate physical or logical interfaces to maintain traffic separation between all MPLS L3VPNs.

    &lt;VulnDiscussion&gt;The primary security model for an MPLS L3VPN infrastructure is traffic separation. The service provider must guarantee the cu...

  • The Juniper PE router must be configured to have each Virtual Routing and Forwarding (VRF) instance with the appropriate Route Target (RT).

    &lt;VulnDiscussion&gt;The primary security model for an MPLS L3VPN as well as a VRF-lite infrastructure is traffic separation. Each interface can o...

  • The Juniper PE router must be configured to have each VRF with the appropriate Route Distinguisher (RD).

    &lt;VulnDiscussion&gt;An RD provides uniqueness to the customer address spaces within the MPLS L3VPN infrastructure. The concept of the VPN-IPv4 an...

  • 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...
