One of my RB2011 routers crashed after months of up time.
I was running pppoe static IP plus a /29 subnet and a /28 subnet. I asked the ISP to delete the smaller unused /29 subnet. Once they got around to this, one morning the RB2011 crashed and just showed 3 or 4 Ethernet leds blinking all in sync. The deletion of the subnet do doubt changed their advertisements and that likely hosed the router. Last time a saw a RB2011 with ethernet leds pumping out some sort of undocumented error code I had to restore the router completely with Netinstall.
I understand that Winbox is never a good way to restore when possible corruption exists.
But now it won’t stay up after rebooting. So I am going to assume I have a corrupt OS and Netinstall needs to be performed.
I have serial cable console access and firmware is showing as 3.16. Is there any need to move to 3.18?
Also, what steps do I take to ensure a clean install with a stable OS. So before upgrading to 6.19 should I do something else first ?
Any help with this would be very much appreciated.
start this crashing all of a sudden? or after which change it starts? if no config change was done. take a spare router and import the config. if the problem gone it’s most probably a hardware issue.
