    Group
  • The Cisco 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...

    Group
  • The Cisco PE router providing MPLS Layer 2 Virtual Private Network (L2VPN) services must be configured to authenticate targeted Label Distribution Protocol (LDP) sessions used to exchange virtual circuit (VC) information using a FIPS-approved message authentication code algorithm.

    &lt;VulnDiscussion&gt;LDP provides the signaling required for setting up and tearing down pseudowires (virtual circuits used to transport Layer 2 f...

  • The Cisco 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 Cisco PE router providing Virtual Private LAN Services (VPLS) must be configured to have all attachment circuits defined to the virtual forwarding instance (VFI) with the globally unique VPN 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...
