In this document, there are several things that are involved: Fast Reroute Frr--fast Re-route Link protection Node protection Path protection Some other advanced protection mechanisms. Before we begin, we need to understand why protection and recovery are needed. Some of the networks sometimes fail, and these failures involve a wide range of lines, fiber loose/broken to router crashes. In IGP, if network turbulence is encountered, OSPF or other routing protocols recalculate the topology,

In the traffic engineering of MPLS TE, it is divided into the following aspects: 1, the release of information 2, the calculation and establishment of the path 3, traffic forwarding in the tunnel. So here to understand the path calculation and build, first of all to understand how SPF is working, and then see what is CSPF (constrained SPF). In order to establish the calculation of the path is a good understanding. In detail, why do you want to lea

Absrtact: Broadband IP metropolitan Area network, routing planning and design is the core link. In the beginning of the network, must be integrated planning. According to the construction of the metropolitan area Network, the routing strategy based on Bgp/mpls VPN is adopted, which is proved to be feasible by practice. Key words: BGP MPLS VPN IP Routing strategy 1 Broadband metropolitan Area Network overv

The principle of the protection of TE is already mentioned. Today's focus is to explain how the Frr-fast-reroute in Te Protection is configured, and how to look at the state. Before introducing the configuration, it is important to note that FRR fast rerouting is a protection mechanism. Imagine if the R2 to R6 is an ordinary IGP network. After the middle link down, what is the situation? It should be the first problem the router sends the LSA through the other interface and then reddening to

High bandwidth, easy to increase service items, low interference, stable voice quality, low cost, good performance/price ratio. These requirements through Netco

In the HUB-AND-SPOKE environment of mpls vpn, for the sake of security AND cost, the branches are not interconnected, AND the access between the branches must go through the firewall of the headquarters, both the security effect and the cost are saved.The experiment topology is as follows:Due to the existence of the downstream bits and domain tags in the anti-ring mechanism of OSPF, the route may not be received in the outbound VRF of r6. therefore, t

MPLS (Multi-propocol Label Switching) is a Multi-Protocol Label exchange.MPLS is a third-generation network architecture and a new generation of IP High-Speed Backbone Network Exchange Standard, proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Group, led by Cisco, ascend, 3Com, and other network equipment manufacturers.MPLS is an integrated IP over ATM technology. It combines routing functions on Frame Relay and ATM switch,

, which is intercepted by the owner proxy and encapsulated through a IPv6-in-IPv6) tunnel to the current transfer address of the mobile node. When a mobile node receives a packet encapsulated by a IPv6-in-IPv6, it sends a binding update message. If the entry LER receives the Binding Update message from the mobile node, it initiates the LSP operation between the entry LER and the exit LER. The IP-in-IP tunneling technology of the original Mobile IP protocol has a high header overhead and heavy lo

This article is about troubleshooting MPLS ldp. Two devices establish direct-attached LDP neighbors: R2 and R3.r2 's interface Giga 2/0 and R3 interface to establish the LDP's direct-link neighbors. First, review the LDP's neighbor establishment process: LDP utility is the UDP/TCP Port 646来 discovers the neighbor's. So in the future troubleshooting, if the two sides can ping, but can not build a neighbor to check whether the port has been sealed

What is the premise of using MPLS traffic engineering for CISCO? or MPLS te configuration logic: Cisco IOS software version that supports MPLS traffic engineering. The network needs to start CEF. The link state protocol used as IGP OSPF or Is-is. Only these two protocols can support TE. (OSPF provides a class tenth LSA to propagate related TE information). Th

1 Introduction The structure of MPLSMultiprotocol Label Switching protocol is described in [1. A label exchange router can be used for Frame Relay switching. Frame relay switches the routing algorithms at the network layer, such as OSPF, IS-IS, and forward data based on these routing algorithms. You do not need to select a specific frame relay path.Frame Relay switching applies to the top-level current tags in the first DLCIData Link Connection Identifier Field of the frame relay data Link layer

?? In the network environment, in order to isolate and divide the network, avoid inter-network interference and broadcast storms, define a variety of forms of isolation. There are hardware-based isolation and network protocol isolation, as well as the isolation of subnet segments (subnet masks).?? MPLS and VLAN isolation, based on the software protocol, there is a certain hardware technical support, with these two tags of the packet, before or after t
