mpls pricing

1. With the advances in hardware technology and the creation of high-speed routers and three-layer switches, MPLS has had little meaning to increase the speed of forwarding. However, MPLS has been widely used in virtual private network, traffic engineering, QoS and so on because of its support of tag stack and connection-oriented characteristics. MPLS Label switc

The previous document has already learned the information dissemination through OSPF, also introduced the CSPF and path's establishment RSVP work principle. What should we do next? You can forward customer data traffic along the tunnel interface in three ways: Static routing routes Policy Routing Policy Routing Automatic routing Autoroute So to be more blunt, this piece of content is the final phase of Te Tunnel, the key to the key. Just imagine, through arduous, established a te tunnel, b

In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward VPN traffic between the VPN user sites. The main purpose of thi

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

Before learning MPLS, you should know that MPLS has two modes of operation. 1, Frame mode--gt; in the third-level group header (such as IP packet header) before the tag to forward. 2.---gt; in the MPLS network composed of ATM LSR, MPLS is used to exchange Vpi/vci information in the control plane instead of using ATM

VPN instance changes, the changed PE device should take the initiative to send the BGP refresh packet to refresh the VPN route, and use the new RT attribute to filter the route. Different from RD, We can configure multiple RT attributes for a VPN instance, and the RT attributes are released in the extended group attributes of the bgp update message. The format is similar to that of common group attributes. When a route carries multiple extended group attributes and RT attributes at the same tim

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

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

, 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
