Intranet interaction and the other for isp interaction. the actual topology is as follows: the isp line is directly connected to the vswitch, instead of the vro. The vro is also connected to a port of the vswitch. Its function is only for nat, re-encapsulate the original address of the package and the destination address of the returned package (see the original post). If the Intranet host wants to send pa

time we can configure the router protocol, so that the intranet can reach the router.8, configure the IP address of the ISP router, and test whether the ROUTE0 can ping the IP address of the ISP 202.1.1.2; Also test whether the intranet host can ping the IP address of the ISP router.9, Intranet is not able to ping the router IP address of the

completed and the upper device connection. General Wireless Router WAN port can support ADSL virtual dial-up (PPPoE), dynamic IP (dynamicipaddress, such as Fttx+lan access, Dsl+lan access, etc.), static IP (staticipaddress, such as the Green Line access) and other broadband access mode. And the powerful wireless router WAN port can also support the special L2TP, PPTP, 802.1x+ dynamic IP, 802.1x+ static IP and other Internet access mode. to set up the WAN port, you need to enter the IP a

I want these lines connected to the Internet to be load-balanced and to provide business-transfer functionality when a single line fails. I don't know how to set this configuration.

is done. This part of current is harmonic or reactive current, which is caused by load characteristics. It is important to understand that the VA value is larger than the W value because of this current, and the W value is considered as a special case when the power factor is 1. The W-watt value of a computer is 60 ~ of its va value ~ 70%, in fact, all the modern computer's switching power supply is capacitive, and its power factor value is 0.6 ~ 0.7. Individual machines tend to be 0.6, while m

Misunderstanding 2: confusion between rated power and maximum power The rated power is the power that the power supply can run stably and safely. The maximum power is generally used to cope with sudden high power demands. If the power supply is output at
