I am after some advice as to the best way to confugre VRF Lite with Global RT access. I will be installing a Cisco router soon to terminate new VRF customers via PPP, Ethernet etc.
I have a customer who has a dozen or so sites, each with their own /24 internal network. I have the config working fine for routing within the VRF but I want to offer this customer Internet access via Global Routing Table. I understand I can leak the routes via static or BGP, however, what if I get another customer come along who will be using the same subnet within their VRF. For example CustA-192.168.10.0/24 is used at one of the sites, what if CustB wants to use 192.168.10.0/24 for one of their sites?
Little confused at the moment! Thanks.
