Why Communication with the Destination Network Fails After a Route to the Destination Network Is Configured on a Device?

As shown in Figure 1, TerminalA cannot communicate with ServerB after a route to the network segment 10.2.2.0/24 of ServerB is configured on SwitchA.

Communication between TerminalA and ServerB is bidirectional. SwitchA must have a route to 10.2.2.0/24, and SwitchB must have a route to 10.1.1.0/24. After a route to the network segment 10.2.2.0/24 of ServerB is configured on SwitchA, you also need to configure a route to the network segment 10.1.1.0/24 of TerminalA on SwitchB. TerminalA and ServerB can communicate with each other only when they have routes to each other.

I am very interested for this post, Thanks for you sharing . I have a suggest ,The intermediate Layer 2 device must release the service VLAN. It is recommended that the device configuration be checked first when it is deployed.

Communication with the Destination Network Fails After a Route to the Destination Network Is Configured on a Device. It can be described as a word and a classic sentence, which is a model that my generation should learn. I am very interested for this post, which is very helpful to our daily troubleshooting.
