How do CSC VPN services use BGP to support connectivity between customer sites?

BGP uses address families for IPv6 support in networks that use IPv4 and IPv6 between customers in different geographies.

The BGP AS-Override feature allows the CSC network to use the same autonomous system number.

BGP eliminates the need for an IGP to run within the backbone carrier core and provides more efficient label distribution.

BGP sends labels to the CSC-PE router so that traffic can traverse the backbone carrier.
