Reset default IP address to a RB-450G Mini router

by User1234 » Fri Mar 25, 2011 10:54 pm

I was told my 3 routers were cleared and set to a default IP address. Can someone help me identify:

A: What is the default IP address
B: If it ISN'T at default, what are the procedures to default it
C: If I cannot default it to a predetermined IP address, how can I find out what IP address is assigned in the router

Thanks all for your support

a: on that router, I believe it is DHCP on the WAN interface (ether1), and on the LAN interface (ether2). You can look it up on the box it shipped in, or reset in hardware as described in b) and then access via serial console and look at IP configuration.
b: "/system reset-configuration" if you can access it (IP, MAC, or serial console), or follow the instructions for a software reset by shorting the reset hole as described in the device's hardware manual (
c: if you're unsure it's always best to use the serial console.
Specific answers require specific questions. When in doubt, post the output of "/ip address print detail", "/ip route print detail", "/interface print detail", "/ip firewall export", and an accurate network diagram.
