LM809M3X-2.45 Article About

Present between the PE and CE can support only four routing protocols BGP, OSPF, RIP2 or static routing. Through MP-BGP protocol with each VPN router to learn the user to the correct route, and now look at how to forward user data. 1.CE1 sent to receives the IP data packet, the query routing table and sends the IP packet to PE1. 2.PE1 received from the S1 port on IP data packet, according to S1 where the VRF, check the corresponding CEF table, packets marked with tags 8, note that the label is through the MP-BGP protocol coming from. PE1 continue to query the global CEF table, should be informed of data sent to, you must first be sent to PE2, and to be sent to PE2, it must inform the tab marked by the P1 2. So the IP packet is marked with two labels. 3.P1 label packages received after the analysis of the top label, the label into the top 4, continue to send the P2. 4.P2 and do the same as the operation of P1, due to the pop-up mechanism to the second last relay, P2 remove the label 4, with only a label directly to the label packages sent PE2. 5.PE2 receive the label package, analysis of labeling head, as the label 8 is its locally generated, and is the only local, so very easy to check 6.CE2 PE2 access IP data packets, routing lookup, the data sent to the / 8 network segment.
New Holux GPS53CL SiRF Star chip abandoned in favor of Mediatek MT3318, and the brand in the GPS chip and the former of which the application is not extensive, the higher the performance improvement will also still be fine. In other respects, the two products maintained a striking similarity: the same appearance, the same is 170 grams of weight, 400MHz processor, 3.5 inch touch screen, the other with SD / MMC card slot, supports mp3 playback, in addition to can be used to view images. Bluetooth is still not a standard product, but if necessary can also be added, cost the U.S. a clear message no. Similarly, time to market this product and whether the price will be higher than the old models are still unknown. 3.5-inch GPS market which, 4.3 inch and 7-inch navigation device everywhere, but 4.8 inches car GPS would be very rare. Shinco GM-4810 Car Navigation System with 4.8 inch wide screen, and Bluetooth capabilities, built-in high-de navigation map, the latest offer for 3350 yuan.
