# The Spines actually don't care about this though, each of them learns the VRRP virtual MAC on it's directly connected CR port. Because they are not learning the remote one over BGP they don't complain about a duplicate MAC:

# In fact the Leaf is going to ECMP between these two, so it turns the normal VRRP active/passive traffic path into an active/active one.
