How to reload router in Dynamips
January 1, 2008 at 11:29 pm | Posted in Dynamips | Leave a commentThe IOS reload command is not suppored by dynamips in virtual routers. So you can use the Dynagen reload command. It performs a stop, followed by a start. To reload all routers in the entire lab, issue a reload /all:
reload R1
To let the router to start with the save config, you need to remove the initial config in your Net file. For instance
# cnfg = C:\Program Files\Dynamips\sample_labs\internetworkexpert \initial.configs\R1.initial.config.txt
Alternatively, before you reload your router,
– wr mem your config to nvram (using IOS CLI) and
– export it to a directory (using Dynagen CLI) .
Then
– reload with normal initial config (using Dynagen CLI) and
– import the “saved config” from the save directory to your start-up config (using Dynagen CLI) .
– configure replace to override the running config with the startup config (using IOS CLI).
