The following minimal configuration is applied on all inter-provider device links. Here are two key MPLS resources: The Juniper TechLibrary is stuffed with MPLS information for Junos and for indi-vidual hardware platforms. If there is a link or node failure in the core network, a protection mechanism such as MPLS fast reroute can be triggered on the transport LSPs between the PE routers to repair the connection within tens of milliseconds. In a traditional network, each switch performs an IP routing lookup, determines a next-hop based on its routing table, and then forwards a packet to that next-hop. Example: Configuring MACsec over an MPLS CCC on EX Series Switches | Junos OS | Juniper Networks MAC-VRF unifies EVPN E-LAN services configuration across all Juniper platforms for EVPN - MPLS or EVPN-VXLAN.

Step-by-step instructions are provided for each device in the example configuration. If the MPLS protocol is not configured correctly on the routers in your network, the interfaces are not able to perform MPLS switching. The topology is shown in Figure 1 and Figure 2. Distributed Enterprise Connectivity Architecture Design Considerations. To implement Ethernet over MPLS, you must configure a Layer 2 circuit on the provider edge (PE) switches. (also referred to as next-generation Layer 3 multicast VPNs) • Family any (for family any, ccc, ethernet-switching, or mpls) When a customer edge (CE) device in an Ethernet VPN-Multiprotocol Label Switching (EVPN-MPLS) environment is multihomed to two or more provider edge (PE) devices, the set of Ethernet links that connect the devices comprise an Ethernet segment. Table 1 shows the addresses for the router interfaces in the example topology. The PE routers PE1 and PE2 are connected to one another by LSPs enabled across a service provider backbone running MPLS, BGP, RSVP, and OSPF. This example details the steps required to configure broadband edge seamless MPLS with head-end termination for residential subscriber management deployment. 2.

Device and Link Redundancy Overview. This is not needed on the PE-CE links. When you first install Junos OS on your device, MPLS is disabled by default. The LSP tends to follow the shortest path as dictated by the local routing table, usually taking the same path as destination-based, best-effort traffic. This example shows how to configure next-generation VPLS (NG_VPLS) using point-to-multipoint LSPs. This example is an introduction in how to rewrite (remark) DSCP class-of-service (CoS) code point values at the network border of a customer network and a service provider’s MPLS network while maintaining the original CoS profile of the traffic so that the traffic can be remarked with the original DSCP code points when it exits the MPLS network.

Multiprotocol Label Switching (MPLS) is a protocol that uses labels to route packets instead of using IP addresses. Key MPLS Resources There are literally hundreds of MPLS books out there, but not many of them deal with the Junos OS. 1. VLANs are configured in this example. RFC 5654, Requirements of an MPLS Transport Profile, describes the requirements for the MPLS Transport Profile (MPLS-TP) that extends capabilities for Operation, Administration, and Maintenance (OAM) when MPLS is used for transport services and transport network operations.

To implement MPLS, you must configure at least one provider switch as a transit switch for the MPLS packets. 0. An LSP is initiated on Router 0 with a strict path travelling through Router 1, Router 2, Router 3, and Router 4. An Ethernet segment identifier (ESI) is a 10-octet integer that identifies this segment. In Figure 1, a Layer 2 circuit is established between routers PE1 and PE2 to deliver Layer 2 traffic between customer routers CE1 and CE2. However, while CCC requires the same Layer 2 encapsulations on both sides of a router (such as Point-to-Point Protocol [PPP] or Frame Relay-to-Frame Relay), TCC lets you connect different types of Layer 2 protocols interchangeably. Configuration and verification steps are included, as are troubleshooting strategies to employ if the configuration is not working properly. In the example, we have applied the filter in the input direction. No special configuration is required on the customer edge (CE) switches. 11 This example shows how to enable MACsec to secure sensitive traffic traveling from a user at one site to a user at another site over a basic MPLS CCC.

Technically, the command “mpls ip” is also needed at the global configuration level but IOS has this command configured as a default so it does not need to be explicitly entered. Enable packet-mode processing. The primary LDP instance is configured at the [edit protocols] hierarchy level. These are driven by the service provider requirements, RFC compliance, and design choices. SRX-A This example shows how to configure an active-active multihomed customer edge (CE) devices and provider edge (PE) devices in an Ethernet VPN (EVPN). 6 Translational cross-connect (TCC) allows you to forward traffic between a variety of Layer 2 protocols or circuits. For example, watching some instructional videos I see that when configuring MVPN that you must use this command which I do not know why, while in other configurations such as L2/L3 VPN i don't see it configured. The LSP metric is used to indicate the ease or difficulty of sending traffic over a particular LSP. Example: Configuring a Single SRX Series Device in a Branch Office. To enable LDP with minimal configuration: Traditional MPLS is designed to carry Layer 3 IP traffic using established IP-based paths and associating these paths with arbitrarily assigned labels.

Figure 1, shows two VPLS mesh groups: LDP-1 and the default BGP mesh group. Commit script macros process the custom configuration syntax and expand it into standard Junos OS configuration statements, which are then added as a persistent or transient change. Establish detours for the LSP so that if a node or link in the LSP fails, the traffic on the LSP can be rerouted with minimal packet loss. MPLS LSP Link Protection and Node-Link Protection System Requirements.

These labels can be configured explicitly by a network administrator, or can be dynamically assigned by means of a protocol such as LDP or RSVP. Greetings all, I am a bit confused as to the purpose of the vrf-table-label command when it comes to MPLS configuration. Providers can segregate different customers’ VLAN traffic on a link (for example, if the customers use overlapping VLAN IDs) or bundle different customer VLANs into a single service VLAN. The CoS value is included within the MPLS label, which is passed through the network, enabling end-to-end CoS across the network. Traffic engineering moves flows from congested links to alternate links that would not be selected by the automatically computed destination-based shortest path. Example: Configuring MPLS over GRE with IPsec Fragmentation and Reassembly. Aug 31, 2023 · Example: Configuring MPLS LSP Link Protection | 12 Example: Node-Link Protection Configuration | 40.

To implement link protection, include the link-protection statement on the primary LSP at the ingress point and on the appropriate downstream RSVP interfaces you wish to protect. 0 Figure 1 shows an example of how you can implement node-link protection. Complete Configuration Repository on GitHub: https://github. It contains the following sections: Enable MPLS on the switch. The two PE routers build MPLS/BGP adjacencies to one another to exchange label information and build the LSPs for the two VRFs. Traffic engineering allows you to control the path that data packets follow, bypassing the standard routing model, which uses routing tables. Requirements. This functionality might be used by a VPN customer who has connections to several different service providers, or different connections to the same service provider in different geographic regions, each of which has a different AS. Lower LSP metric values (lower cost) increase the likelihood of an LSP being used.
