problem in interconnection between equipment manufacturers. Therefore, deploying gre vpn in a common IP network is a good choice. Technical solution 3: MPLS VPN Figure 4 network service platform deployment using MPLS VPN As shown in figure 4, the network service platform deploys mpls vpn on the edge router to multiple points.

router, that is, the Label Edge Router LER In the MPLS network ), it processes the VPN data from the CE router or the label exchange path LSP according to the stored route information and forwards the data. It is also responsible for exchanging route information with other PE routers; P router is the main router of the carrier network, that is, the label exchange router LSR In the MPLS network. It transpar

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution t

-point connections between sites can be achieved through IPSec, GRE, frame relay, and ATM circuits. Each site has a vro that connects to other sites through a point-to-point connection. A site can have one or more such vrouters, and do not connect to all or some other sites. IPsec-based secure VPN is widely used. BGP/MPLS is the mainstream peer-to-peer VPN technology. Mplsvpn uses

formats of broadcast and P2P Hello packets in ISIS are different;L1 and L2 layers are independent;The LSP for normal router multicast. When DIS receives the LSP, it summarizes and broadcasts it to the group;DIS sends brief information with CSNP. The following vro receives a list of items that are missing after comparison, sends a connection details to DIS through PSNP, And Then DIS responds with PSNP;PSNP can also respond to LSP as ACK;Circuit ID is used to identify each port in one byte;The la

is developed from switches, and GSR internally splits data into standard cell exchanges, in terms of queue and scheduling, GSR is better as a pure core router because it has been tested for many years. In terms of price, 7609 is still relatively expensive, while GSR is cheaper in some cases. 2. Which route table of ISIS level1 includes? When there are multiple levels-1-2 exits, Where do other routes learn from and how do I select routes? A: Isis level1 and level2 maintain LSD and SPF. level1's

sites for different SPS. However, as part of the mutual trust protocol between SPS, VPN-IPV4 routing can only be accepted by EBGP connections between private peers. Vpn-ipv4 routing cannot be distributed on the public Internet or accepted by the public Internet. If the sites of many VPN configuration instances are connected to different autonomous systems, there is no need for a ASBR of all VPN routes between the different autonomous systems, and there can be multiple asbr, each ASBR only part

protocol from OSPF and BGP) to map IP groups to Layer 2 exchange channels, through ISR devices and networks, it becomes the first IP exchange mechanism to introduce aggregation and switching channels. Between multiple different sources and the same destination, ARIS can establish a multi-point-to-point exchange path, thus reducing the consumption of switch resources. For layer-3 switches, it is difficult for companies to connect to each other because

the design and production of high-density interface boards and the implementation of high-speed interfaces greater than/equal to 2.5 Gbps.Routing Protocol The realization of router routing protocol is an important part of router software. The routing protocol is used to establish and maintain a route table. The route table is used to select the output port or next hop address for each IP packet. Open routing protocols include RIP/r00002, OSPF, IS-IS, and BGP4.RIP/RIPv2, OSPF, and IS-IS are used
