(TIL) Today I Learned...

TIL that there is a lot about BGP that I do not know.

TIL that I've been filling out my timecard all wrong. 

Timecard?  I thought it was a base requirement to enslave an engineer with a salary!

We fill out our time allocation so that the higher-ups can determine if we're allocated properly, or if they need to allocate more resources.

We do the same at my company.  This way the business knows which department to bill for our services.  I work for a large retail company and IT does not create revenue(even though the business can't run without us) so we have to get our funds from somewhere

Yeah... I used to do this too as a subcontractor...

TIL how to configure CIMC on a Cisco C220 series server
(note to future self, do not use the same IP for the server and for the CIMC configuration)

CIMC has saved my bacon more than once.

TIL that when learning the same (external) prefixes in different OSPF processes, the cost is not the differentiator 

[wintermute000]

do elaborate? I would assume the costs are irrelevant as they fight it out in different OSPF DBs, so it would come down to administrative distance and if equal, route will load balance?

[SimonV]

AD was the same for both processes, and it was actually the lowest process number that won. I would have guessed the cost. But we ended up increasing the AD on one process which fixed the issue

I'm sure it will be on the TS lab!!

Do you guys know if you can setup the CIMC on a Cisco C240 M3 if it has never been setup without taking down the server?

You will need to reboot the server and enter the CIMC configuration utility to setup CIMC.

It would be really handy if CIMC would pick up a DHCP address so you could set i up later, in case you forgot. I know I have missed it once or twice, and sometimes taking the server down isn't an option during the day.

TIL that having two VMs with the same MAC address and same IP address can cause problems on the network when trying to reach said IP address.
