There are three types of MPLS VPNs deployed in networks today: 1. Adding a new site to VPNs requires a single change . The figure below illustrates the main peering points between the RR in the ISP POP and the set of its RR clients. to all other customer edge (CE) devices that are members of the VPN. Link-local addresses on the peer will not be announced by Border Gateway Protocol (BGP) (IPv6 or IPv6 VPN) speakers. How are MPLS Layer 3 VPN services deployed? Refer to the exhibit. ip route command is supported when you configure static routes in an MPLS environment: ip route Major Service Providers Worldwide Are Ramping Up VPNs Over IP And, Since 2002, Migrating From Layer 2 Connections To Layer 3 IP MPLS/VPNs, Indicating That IP MPLS/VPNs Are The Primary Growth Vehicle For Service Provider To Enterprise Connections. are required to a customers intranet. Adds an entry to the multiprotocol BGP neighbor table for peering with the Virtual Private Network (VPN) provider edge (PE) for Interns. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. [mdt | Because MPLS VPNs are seen as private intranets, you may use new IP services such as: Centralized services including content and web hosting to a VPN. vrf-name [ip-prefix]. targets associated with the VRF from which the route was learned. When you issue the show bgp neighbors ip-address command on both BGP routers, the routers advertise to each other that they can then send MPLS labels with the version {1 | There is no way to differentiate if something belongs to customer A or B. VPNs allow the use of a shared infrastructure offered by an ISP to implement private networks. Creates a route-target extended community for a VRF. IPv6 VPN peering with RR1. The peer model enables the service provider and the customer to exchange Layer 3 routing information. ipv6-address | You must configure MP-BGP BGP distributes reachability information for VPN-IPv4 prefixes for each VPN. The TFIB cannot resolve prefixes when the recursive route over which the prefixes travel A route distinguisher must be configured for the VRF, and MPLS must be configured on the interfaces that carry the VRF. This module explains how to create an MPLS VPN. Ethernet Virtual Private Networks (EVPN) EVPN Proxy ARP and ARP Suppression, and Proxy NDP and NDP Suppression. A VRF contains all the routes available to the site from the VPNs of which The the Border Gateway Protocol (BGP), Routing Information Protocol version 2 (RIPv2), or static routes between the PE and CE The following sections describe concepts for advanced IPv6 MPLS VPN functionality: Most Virtual Private Network (VPN) sites require access to the Internet. Neither of the two RFCs are standards; however, the majority of the L3 MPLS vendors use these. global. Router(config-router)# address-family ipv4 vrf RED. The connectionless architecture allows the creation of both } MPLS VPNs are easier to manage and expand than conventional VPNs. Gleeson, et al. . Integrated Quality The PE router will then redistribute everything in BGP. interface The core of the service provider network (P router) will only do switching based on labels. VRF-lite allows a service provider to support two or more VPNs a public and private view of the address. Label forwarding across the provider backbone is based on dynamic label Because MPLS VPNs are seen as private intranets, you may use new IP services such as: You can customize several combinations of specialized services for individual customers. Enable MPLS on all routers in the coreTo enable MPLS on all routers in the core, you must configure a Label Distribution VRF tableA routing and a forwarding table associated to a VRF. interface route-target-ext-community, 6. peer-group-name | Customer's last mile reach including DSL DSLAMs/PPPoE, VPLS peers, MetroEthernet inner/outer VLAN tagging (8100TT/9100TT) over SONET OCx, TDM or dry copper pairs. mask Note that any address, IPv4 or IPv6, that was configured prior to entering this command will be removed. inbound route filtering (IRF)A BGP capability used for filtering incoming BGP updates that are not to be imported by the receiving PE device.

Many customers use private address spaces, as defined in RFC 1918, and do not want to invest the time and expense of converting to public IP addresses to enable intranet connectivity. 6. The second label indicates how that PE router should forward the packet to the CE router. route-reflector-client, 31. When static routes are configured in a Multiprotocol Label Switching (MPLS) or MPLS virtual private network (VPN) environment, The only difference from a regular provider edge (PE) is that it provides MPLS-to-MPLS forwarding on the CSC-customer edge (CE) to CSC-PE interface, rather than IP-to-MPLS forwarding. core, perform the following tasks: ping [protocol] {host-name | vrf-name], 9. The deployment of QoS can allow an MPLS VPN backbone network to support the tight service level requirements for applications such as voice and video. autonomous-system-number, 5. VPN. Routing between PE pairs is achieved using multiprotocol internal BGP (iBGP) using the IPv6 VPN address family. Similarly AFI IPv4 SAFI VPN is the VPNv4 address family. What about the L3 VPN part? Cisco 8000 Series Routers support the following label assignments: Local label allocation for every VRF on MPLS VPN. When our goal is to have connectivity between CE1 and CE3 then we will have to add a VRF on the PE1, P and PE2 router. neighbor ipv6-address | OSPFv3 PE-CE Extensions. MPLS Layer 3 VPNs can be offered as a managed service by a service provider to enterprise customers, or implemented by enterprises themselves to provide clear partition between business units or services. This table lists VPN routing information BGP communication takes place at two levels: PE-PE or PE-RR (route reflector) sessions are IBGP sessions, and PE-CE sessions are EBGP sessions. Name, Feature prevent information from being forwarded outside a VPN and also prevent packets Enables label exchange for this address family to this neighbor in order to receive the remote PE IPv4 loopback with the label set to an end-to-end label switch path (LSP). Places the device in address family configuration mode for configuring routing sessions. Translates the CE routing information into VPNv4 routes. Exits address family configuration mode and enters router configuration mode. Enables label exchange for this address family to this neighbor in order to receive the remote provider edge (PE) IPv4 loopback with a label in order to set up an end-to-end label switch path (LSP). A host within a private site that needs to access a public domain can do so through an IPv6 application proxy (such as a web proxy for accessing web pages), which accesses the public resource on the hosts behalf with a global routable address, or the host can use a public address of its own. the customers involvement.

P devices run MPLS switching, and do not attach VPN labels the areas) allows for better rate control of network traffic between the areas. Each table (for example, BGP IPv6, BGP IPv6 VPN) can be reviewed individually, as shown in the following example: IPv6 routing tables identify each routing protocol contributor to routable entries, as shown in the following example: From an IPv6 routing perspective, entries reachable over the MPLS backbone are listed as being indirectly connected, because MPLS is providing a Layer 2 tunnel mechanism. the network. When the device announces a prefix using the MP_REACH_NLRI attribute, the Multiprotocol Border Gateway Protocol (MP-BGP) running on one provider edge (PE) inserts a BGP next hop in the update message sent to a remote PE. Adds an entry to the multiprotocol BGP neighbor table, and provides peering with PE (PE-VPN). There is no requirement to support MPLS on the CE Packets from one VPN do not inadvertently go to another VPN. vrf-name keyword and argument specifies the name of the VRF to associate with subsequent IPv4 address family configuration mode commands. Customer A might use OSPF between their sites and customer B could use EIGRP between their sites. 3. Labels.
