What does the "T" shape mean in network topology? What does the "T" shape mean here? `![enter image description here]( There is a logogram, but I want to know the RTA's left side port whether is config the `192.168.1.0/24` network segment's IP address. This is Quidway technology.

It represents a multi-access local network, such as ethernet. It's just drawn vertically so looks a little unusual.

It shows that the network address on the left is `192.168.1.0/24`, but doesn't specify the address of the interface of RTA. The network on the right of RTB is `192.168.2.0/24`, again without specifying the address of the interface of RTB.
