Explanation:
To support connectivity requirements, the MPLS/VPN architecture supports the concepts of sites, where a VPN is made up of one or multiple sites. A VPN is essentially a collection of sites sharing common routing information, which means that a site may belong to more than one VPN if it holds routes from separate VPNs.
