MC-LAG on vQFX (EVE-NG)

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…
