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

IPsec is designed to solve some basic security problems of IPv4. To solve these problems, it implements four services: Data Transmission encryption, data integrity verification, data source authentication, and data status integrity. To implement these services, IPsec VPN introduces many protocols. In this article, you will learn how to implement the IPsec securit

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

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

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

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

, 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
