2.1.3 Creating a VPN Instance
A VPN instance needs to be associated with a site. A VPN instance does not
correspond to a VPN directly. Instead, a VPN instance is an integration of the VPN
membership and routing rules of its corresponding site.
A VPN instance takes effect only after a route distinguisher (RD) is configured for it. For
a VPN instance with the RD not configured, all the other settings (except the description
information) are inaccessible.
The description information of a VPN instance can be used to record the relationship
between the VPN instance and a VPN.
