How to Configure Router on GNS3 to work with SDM.

Sulaiman Syed Profile: Sulaiman Syed

This is pretty basic configurations that can be done on GNS3 router, or any router that it matters. it is useful for first time users, or who wants to practice CCNA security.

on host do the following settings:

IP address:
Subnet Mask:
Default Gateway:

on the router do the following settings to the interface connecting to your host.

Router> en
Router# conf t
Router(config)# int fa0/0
Router(config-if)#ip address
Router(config-if)#no shut

Now, you need to configure the router to be able

Router(config)# ip domain-name TEST (need domain name setup for sdm)
Router(config)#username test privilege 15 secret 5 TeSt (username / used with SDM)
Router(config)#ip http server (normal http)
Router(config)#ip http secure-server (to enable ssh/https)
Router(config)#ip http authentication local
Router(config)#line vty 0 4
Router(config-line)# login local
Router(config-line)# transport input telnet ssh
Router(config-line)# privilege level 15 (it is recommended to add this line, if not no harm)
Router(config-line)# exit
Router(config)# crypto key gen rsa gen mod 1024

Once this done. the router is ready to be used using SDM. as a side note, if the additional task doesn’t work with your sdm. then just change to older java version, it solves this problem.
