This command makes sure that any outbound telnet sessions are sourced using the loopback interface address.

If you do not configure this command, the routing table is looked up and the address of the outgoing interface towards the destination address is used as the source address for the telnet session. The fact that the source address is not always the same might be an issue when building and ACL.
