GNS3 Dynamips Appliances

assuming you got GNS3 up and running already

Requirements

make sure you’ve got the i386 flavor of the dynamips package, see the GNS3 install guide

Cisco 7200 Series Router

grab the gns3a appliance

#wget https://raw.githubusercontent.com/GNS3/gns3-registry/master/appliances/cisco-7200.gns3a
#grep filename cisco-7200.gns3a

–or– rather directly from the UI

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

Import ~/Downloads/...

the image has been copied over there

ls -lhF ~/GNS3/images/IOS/
ls -lhF ~gns3/GNS3/images/IOS/

you can now configure the hardware

General / auto start console
Slots / C7200-IO-2FE --> 2 x fa
Slots / PA-GE --> 2 x gi

Cisco 3725 Multiservice Access Router

same as above

c3725-adventerprisek9-mz.124-15.T14.image
# 64f8c427ed48fd21bd02cf1ff254c4eb
