I almost complete the step-by-step guide in order to build a Cisco SD-WAN Lab using EVE-NG
It contains initial/basic configs for controllers, vedges and legacy devices. Moreover, it includes all the certificates part which is the trickiest IMHO
I'll publish it in a couple of days

Today I want to tell you about a happy ending story.
On August 12 I took and failed the SD-WAN exam with 814/1000
This morning, after 45d of hard work and study, I took the exam and I passed it.
I took all the bad vibes and converted into positive energy.
Thank you all 🙏🏼

Good news!🎉 The Ansible playbook works and it now retrieves data from external files!
If you are working with Cisco ACI you know that the EPG propagation to port/PC/vPC is a very annoying and boring task, so I wanted to automate it!

cool thing:
I am implementing two Direct Connet between two datacenters and AWS.
Both DCs advertise the same prefixes to AWS, but I want to prefer DC1 over DC2 for some prefixes and vice versa for others.
AWS has a default BGP communities to manipulate outbound traffic

In the next few weeks, I'll deploy my first Cisco VXLAN BGP EVPN fabric with NDFC. It's a greenfield solution, I'm excited
In the last three years, I deployed/managed ACI fabrics and standard DC fabrics with NX-OS, never with NDFC (formerly DCNM)

For notes, I'll use onenote, but I'm not sure if it's the best tool. Suggestions?

*premise* : you have all the necessary SFP and cables for both solutions.
Why should I prefer single-homed vs dual-homed? I don't see any advantage here...with single-homed if you lose your parent switch you're fucked, with dual-homed simply don't... Am I missing something?

Today I did a migration with some Test VLANs from legacy to ACI fabric. I love to show the customer some real scenarios before they go live and prepare them all the necessary tests, especially with these "new" technologies.

If you do not specify the vpc ID under port-channel but just type
---
interface port-channel5
vpc
---
It will automatically inherit the port channel ID (5 in this case) reducing the percentage of misconfiguration
