SSH connection between an MPLS Manager host and an MPLS-enabled device shows an SSH connection between a client and a server.
The client is the SSH client software that connects users to the SSH server on the remote host. The server is the SSH server program, or ssh daemon, that is running on the remote host. In Figure 33, the client and server enable a user named MPLSUser on an MPLS Topology Server host to log in as ServerUser on an MPLS-enabled device.
SSH authentication begins with the authentication of the server to the client, and ends with the authentication of the client to the server.
