[cisco-voip] VRF and when/why to use it

[Han Solo]

VRF provides a L3 abstraction boundary between the physical  
infrastucture / topology and L3 protocols , very similiar how Vlan's  
provide L2 abstraction within the same physical device. We commonly  
use VRF's  business reason of common infrastructure but still have  
admin boundaries within the organization so that each Business Unit  
can have flexibility . Also very commonly used within the Data Center  
to provide isolation for security boundaries .. I think of them as  
Vlans and the same benefit that brought as a design tool VRF's do but  
at another layer.
