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

R0 creates a tunnel to R1 to enable multicast. It's very simple to scale up and you can see the configuration at first glance. Wvrp has passed.

?? 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

When there is no peer VRF route, VRF uses MPLS *** to transmit routes to each other ,. After the PE routers at both ends use IGP (PIPE) to build a neighbor, a small pipe (*** V4 cluster) is built in the pipe for ** communication MPLS ** key points: IGP physical links and lo interfaces must be built through BGP large and small water pipes, and reflection must be configured under small water pipes.

The baseband signal is the original electrical signal, which generally refers to the basic signal waveform. In digital communication modulation technology, it refers to the corresponding electrical pulse. In Wireless telemetry and remote control systems and radio technology, modulation is to use baseband signals to control parameters (amplitude, frequency, and phase) of high-frequency carriers so that these parameters change with the baseband signals. The baseband signal used to control high-fre

Optical bridge users in the voice of the need to focus on the following areas: the scope of business to be broad, you can achieve voice mail, voicemail, address books and many other functions, can be integrated with the computer, data, voice simultaneous implementation. High bandwidth, easy to increase service items, low interference, stable voice quality, low cost, good performance/price ratio. These requirements through Netco

Currently, ISPs in China mainly include China Telecom, China Netcom (now merged with China Netcom), and China Mobile (already merged with China Tietong), and China Telecom and China Unicom (China Netcom ). Due to the differences between ISPs in the south and the North, ISP restrictions lead to slow access to various websites in the south and north. To solve this problem, the common practice is to obtain the IP address segment of the carrier. by settin

The above section says analog signal analog carrier modulation, this section says the following analog signal digital carrier code. Digital transmission of analog signals The analog signal is sampled-quantified-encoded into a digital signal into the channel transmission Sampling: processing a continuous signal over time into discrete signals in time It should be noted that the Neiguist sampling theorem, tha

the monitor, printer and other peripheral signal is the baseband transmission. Most LANs use baseband transmission, such as Ethernet, Token Ring network. The common network design standard 10BaseT uses the baseband signal. The signals on the parallel bus inside the computer are all baseband signals, which is not suitable for long-distance transmission because of the extremely rich AC components in the baseband signal.　　Simply put, the baseband signal is the low-frequency signal, which is the si

Recently, I have been reading mpls vpn, but I have never understood the differences between the two RD and RT parameters in VRF. By searching materials on the Internet for repeated reading and thinking, I finally understood it. The following uses a more understandable metaphor for sharing. For example, if you receive an invitation letter, you need to go to a high-end office building to attend the meeting. Because of the strict security requirements,

In the MPLS/vpn experiment, the configuration of OSPF/r12002 was developed from the basis of the first experiment, so some basic configurations are not mentioned here. The network topology is as follows: first complete the RIP configuration on CE1: Before you configure this, you must delete the previous configuration. If you do not delete the configuration, the problem may occur. CE1: router rip version 2 network 1.0.0.0 network 192.168.1.0 no auto-su

In order to improve the export bandwidth, many enterprises have applied for broadband multi-line access. However, in actual use, not to apply for more than one line, you can immediately realize the superposition of bandwidth and load balancing. Multi-line bandwidth overlay and line equalization, but also need technical means to implement. In short, multi-line load balancing requires at least the following basic functionality: Multi-line bandwidth overlay based on weights. Since multiple

Dear Big Brother, we have a clear understanding of the GPS reception sensitivity indicators-what are the meanings of carrier C/N and C/no? What are the differences between the two. C/NO = 10 * log (C/KTB), excluding the noise produced by the path loss and LNA routes from the day to the correlator. C/N includes all the noise. C refers to the degree of confidence, K refers to the constant number of waves, T is the degree of attention, an
