in privileged mode type x.x.x.x and you will telnet to x.x.x.x being the ip address of the other router or if you want to ssh then type ssh -l "username" x.x.x.x but of course you must have ssh server enabled on the other router to use this protocol.
To return to intial console just type logout or exit in enabled mode.
