  • Page 37: Pta To Virtual Routing And Forwarding Architecture

    In the figure, an ATM network (with no routing capability) is between the clients and the Cisco 10000 series router. Each client session arrives on a VC (multiple sessions and PCs can use this single VC). The IP traffic of the client is encapsulated in PPPoX. The Cisco 10000 series router terminates the PPP sessions and routes the client data packets toward their final destination, typically onto the ISP or corporate network.
  • Page 38: Pta To Multiprotocol Label Switching Virtual Private Network Architecture

    In this model, the Cisco 10000 series router terminates the sessions and places the sessions in the appropriate VRF. This model is identical to the one in Figure 1-3 on the access side. However, the two models differ on the network side.

    In the figure, an ATM network (with no routing capability) is between the clients and the Cisco 10000 series router. Each client session arrives on a VC (multiple sessions and PCs can use this single VC). IP traffic of the client is encapsulated in RBE. The Cisco 10000 series router processes ARP or DHCP requests and routes the client data packets toward their final destination, typically onto the ISP or corporate network.

    PPP or HDLC SONET/SDH In a typical Cisco 10000 series router application, the provider usually situates the aggregator in a centrally located POP and backhauls individual customer connections from central offices across the SONET/SDH networks. Add-drop multiplexers at either end of the optical network that provide aggregation of low-speed customer connections (T1/E1) and aggregation into higher-order optical interfaces in the central POP.
  • Page 45: Atm Aggregation

    REC 1483 SONET/SDH When used as an ATM aggregator, the Cisco 10000 series router is usually placed in a central POP and connected to a local ATM switching node through optical interfaces. ATM virtual circuits are terminated on the device, and customer IP traffic destined for the Internet or VPN is routed onto the core network.
  • Page 46: Ethernet Aggregation

    The “build once, sell many” approach of the network design provides scalability and flexibility with respect to VPN products and services. MPLS provider edge functions and associated features and services are offered on the Cisco 10000 series router, spanning all interfaces and encapsulations from low-speed broadband to traditional leased-line applications to high-speed Ethernet.

    PE router, the PE router locally switches the spokes without passing the traffic through the upstream Internet service provider (ISP). In releases earlier than Cisco IOS Release 12.2(16)BX2, when spokes connect to the same PE router, it was necessary to configure each spoke in a separate VRF to ensure that the traffic between the spokes always traverses the central link between the wholesale service provider and the ISP.

    The default route points to the interface on the hub PE router that connects to the upstream ISP. The Cisco 10000 series router dynamically learns about the default route from the routing updates that the hub PE router or home gateway sends.

    Configuring Multiprotocol Label Switching Half-Duplex VRF The Cisco 10000 series router redistributes routes from the downstream VRF into Multiprotocol Border Gateway Protocol (MP-BGP).

    Processing IP options packets in the RP can become problematic. Software-switching of IP options packets can lead to a serious security problem if a Cisco IOS router comes under a DoS attack by a hacker sending large streams of packets with IP options. The RP can easily become overloaded and drop high priority or routing protocol packets.
