MIS with MPLS Private Network Transport PNT

With the MPLS PNT feature, AT&T segregates Customer data traffic transmitted over the AT&T IP Network using MPLS to create a network-based IP Virtual Private Network (VPN).? AT&T segregates Customer's PNT traffic from other traffic on the network with separate routing tables in AT&T network/provider edge (PE) routers. Unique VPN ID labels are added to Customer's data packets as they enter the AT&T IP Network and are removed as the data packets reach their destination so that the Customer's router may read the data. PNT does not permit access to the Internet, so Customers must order separate MIS ports if they also want Internet access and DNS Administration, Network Newsfeed Service or Outbound Mail Relay Service at an MIS with PNT Site.? The MPLS PNT feature is available for use at Sites with Local Channel access (Full/Fractional DS-1, Full/Fractional DS-3, OC3, OC12, and OC-48).

MPLS PNT Service Types:

• MPLS PNT IP Transport
  With MPLS PNT IP Transport, MPLS label stacking starts at the AT&T's MPLS-enabled Provider Edge (PE) routers, and MPLS and other enabling technologies are used within the AT&T IP Network to join Customer?s MPLS PNT Sites into a VPN.? Customer traffic sent between the Customer edge (CE) router at the Customer Site and the AT&T PE router over the local access circuit is not segregated using MPLS labels, but AT&T supports static routing or BGP 4 between the CE router and the AT&T PE router.
• MPLS PNT Label Transport
  With MPLS PNT Label Transport, Customer CE routers and AT&T PE routers are configured for IP static routing and Label Distribution Protocol (LDP) to allow the exchange of MPLS labeled traffic between Customer CE router and the AT&T PE router over the local access circuit. MPLS label stacking starts at the Customer's router, so Customer network information associated with Customer?s end user customers is not visible to AT&T.? MPLS PNT Label Transport also enables Customers to offer MPLS VPN capabilities to their end-user customers.
