Golang API
Golang NET package has a very convenient API for us to use, this API can be divided into Addr,listen,connection,dialer,ip and other network APIs, such as DNS API, etc. There are no other Web APIs (mainly self-study _).
Addr mainly have ipaddr,tcpaddr,udpaddr an

dial-up network by mistake, especially on the backup network, causing unnecessary troubles. Therefore, generally, the vroeigrp that runs the OSPF Protocol needs to configure Dialer list and Dialer group on the dial-up backup port to filter unnecessary packets or run the TRIP protocol. This increases the overhead of the vro operation. OSPF supports on-demand dial-up on the dial-up network. Only one routing

PPPoE has always been a key point in vro settings. Today, we will analyze and introduce the PPPoE setting process on the 2600 router. First, we will take a look at the configured network environment based on the network topology, and then parse the specific code.

, especially on the backup network, causing unnecessary troubles. Therefore, generally, when a router running the VPN gateway is configured with the Dialer list and Dialer group on the dial-up backup port, it can filter unnecessary packets or run the dynamic routing protocol for the TRIP, in this way, the router operation overhead is increased. OSPF supports on-demand dial-up on the dial-up network. It can
