make sure you’ve got the i386 flavor of the dynamips

New template --> install an appliance from GNS3 server Routers --> Cisco 7200
and grab the image from some place – you might find something close and it’s good enough
c7200-adventerprisek9-mz.124-24.T5.image # 6b89d0d804e1f2bb5b8bda66b5692047
and setup additional parms
general / default name format: C3725-{0} auto start console
same as above
c3725-adventerprisek9-mz.124-15.T14.image # 64f8c427ed48fd21bd02cf1ff254c4eb
and setup additional parms
general / default name format: C7200-{0} auto start console
you can now configure the hardware
slot 0: C7200-IO-2FE (2 x fa) slot 1: PA-GE (2 x gi)
slot 0: GT96100-FW (no other choice) slot 1: ?
