Hi,

Regarding this:

> There are multiple methods for load balancing:
> 
> Round-robin: the AVG will hand out the virtual MAC address of AVF1, then AVF2, AVF3 and gets back to AVF1 etc.  
> Host-dependent: A host will be able to use the same virtual MAC address of an AVF as long as it is reachable.  
> Weighted: If you want some AVFs to forward more traffic than others you can assign them a different weight.

I’m not sure to understand the difference between glbp priority and glbp weighting.

Also I’ve tried to replicate this lab but I think that a routing loop is occurring during pinging the loopback of R1.

can you help me?

Here my captures and a picture of my topology
