Hi all,

today I’m gonna show you how to implement MC-LAG on the vQFX (QFX10k codebase) on EVE-NG. I personally found this pretty straight forward to configure but since I recieved so many Mails asking me to show this, I will do.

Here’s the very simple Topology (click to enlarge):

And here’s the Code – as you can see it’s not that hard but you have to remember some things:

When configuring MC-LAG always remember that the following settings must match on both Members of the MC-LAG:

LACP System-ID + Key
MC-AE ID + Mode
VLAN’s (ICL and Member VLAN’s)

The following settings must be unique for each Member of the MC-LAG:

MC-AE Chassis-ID + Status Control
ICCP IP (Local) and Peer IP (who would have guessed this…)
MC-LAG Protection 

I will give you more explanation on this Topic later because as you might have heard my JNCIE-DC is booked for the 14th of February (therefore not so much time to write detailed Blogposts) and time is slowly running away… Okay just kidding – time just took a SPRINT towards my deadline… However, my beard looks fine so far…

The final Countdown for the JNCIE-DC

Just 38days of labbing until the JNCIE-DC Exam-Day has arrived.
Exam is already booked and I am so excited to do this (way more than with the first JNCIE because I already know what awaits me in terms of the trip to Amsterdam, the Exam-Room etc.) – and I feel way more confident about the Topics (EVPN really kicks ass) 😉

I would love to share some EVE-NG Topos – however, I only work with the official inetZero Superlabs this time and therefore can’t legally share anything.

After the Exam I will try to develop some Training to share for the SEC and DC-Exams to prep you for the final day – in the meantime –> stay tuned 😉
