I have an old 2600 router that has been in service for at least 5 years. The third party company that installed and deployed is now out of business. The router works but is a mysterious 'black hole' on our network (I am new to this network). I need to review the configuration to determine many things (like what is it doing specifically and how?). I use the rommon mode to get into the router (confreg 2142) but when I issue any command it responds with "Authorization Failed". We do not have any AAA servers running on our network (TACACS, Radius, etc.) so I am suspicious that the old service provider may have some sort of VPN running or perhaps is using a LOCAL database on the router. Can anyone suggest a way that I can view this configuration? THANKS!.
