Distributed Core
VCStack LD (Long Distance) enables the 
VCStack solution to provide a distributed 
network core. The increased distance 
provided by fiber stacking connectivity 
means that members of the virtual 
chassis do not need to be collocated. 
Instead, they can be kilometers apart. 
Diagram 1 shows an example of a long 
distance stack, where the single virtual 
distributed core ensures high availability 
of data for network users.
Network Virtualization
Virtual Routing and Forwarding (VRF 
Lite) allows multiple customers to 
share a common infrastructure, while 
maintaining their own independent 
virtual routing domains. Individual 
customers can take advantage of 
shared resources such as printers and 
Internet access via filtered inter-VRF 
communication, while maintaining 
absolute security. See diagram 2.
