Learning about different SLA's⠀
what service lvl is acceptable for what service, what can be dropped, what needs to be preserved... Now theory, later the practice...⠀

How to tell that you are running Traffic Engineering in your network?⠀
-⠀

-By checking if a new bit, the O-bit is present in the Options field⠀
-By being able to issue the “sh ip ospf database opaque-area” command⠀
-By checking if it supports Opaque LSA’s⠀
-Verifying what information the Opaque LSA holds (resources present on a link)⠀

After a year and a half of building my Dream PC:
#Virtualization using hyper-v.
DMZ #firewall using #pfsense.
LAN firewall using pfsense.
LAN IPS\IDS using snort.
#VPN using openvpn.
Network monitoring using ntop.
#VoIP using freepbx.
Media server using #ubuntu server 18.04.
#Torrent auto download using utorrent.
#Uesnet auto download using SABnzbd.
#Streaming using Plex and kodi.
PVR using sickbeard and couchpotato.
#Minecraft server using MineOS.
Website #hosting using IIS10.
#DDoS protection using cloudflare.
Networking #lab using #GNS3 running on Linux ubuntu 18.04.
Network #security lab using kail.
Cloud #Backups using 1TB onedrive.
And more on the way

MPLS is very easy to set up. It requires CEF and two commands (actually one, entered in two places). Under the global config and under the interface config. And voilà! We have MPLS running :)⠀
-⠀
Although - we can go deeper and fine-tune it, making it resilient, more reliable!⠀

I’ve been asked in the comments about the title of a depictured book. I wrote that post not so long time ago. It was showing a twisted OSPF network with and opened book. The title of that book was: Troubleshooting IP Routing Protocols. One from the CCIE R&S reading list.⠀

You have no idea what can go wrong with a routing protocol…⠀

As VLANs não são armazenadas na NVRAM dos Switches. Se quiser apagar todas as vlans você deve deletar o arquivo vlan.dat que está na memória Flash. <Comando>

Switch#delete flash:vlan.dat

Logo após deletar e reiniciar o Switch, o dispositivo estará com as configurações default (padrão). Com todas as portas na Vlan 1. Obs.: não é possível apagar a Vlan 1.

AToM⠀
I wanted to add one more thing about AToM.⠀
It's very easy to understand and to implement. From a business perspective - you run 2 cables, bill the customer one-off for provisioning and then an RMC for as long as it's needed. Easiest money ever.⠀
