Operating the VPN
Once the VPN is operational, other workflows come into play. Following are some typical operations that the service provider executes during the VPN lifecycle:
Adding sites to a VPN
Removing sites from a VPN
Creating more core LSPs
Updating existing core LSPsfor example, adding more reserved bandwidth
Deleting and replacing core LSPs
Handling faults that affect the VPN service
End users can increasingly initiate VPN-related management workflows as part of customer network management. This function can include facilities that allow VPN users to check connectivity, verify that service-level agreements are being met, and even increase allocated core bandwidth.
