2.3 VPWS Basic Function Configuration

2.3.1 VPWS Overview

VPWS uses point-to-point connection mode to implement communication among each site
within VPN. This mode is usually used for ATM or FR clients. With this mode, connection
between clients and network providers maintain constant, but services encapsulated are
transmitted over IP backbone network of the network provider.
LSP tunnel through MPLS net should be defined between two PE, and it should provide
tunnel label transparently transmitting data between two PE. At the same time, direct
process of LDP label distribution protocol is also defined between two PE routers to
transmit virtual link information. Among them, distributing VC Label through matching
VCID is critical.
When data packet enters PE at the port of Layer 2 transparent transmission, PE finds the
corresponding Tunnel Label and VC Label through matching VCID. PE will put two layers
labels on the data packet. External layer is Tunnel Label indicating the route from this PE
to destination PE. Internal layer is VC Label indicating which corresponding switch port of
VCID belongs to on destination PE.
PE should monitor Layer 2 protocol state at each port, such as FR Local Management
Interface (LMI) and ATM Interim Local Management Interface (ILMI). When a fault occurs,
users can cancel VC Label through LDP label distribution protocol process so that Layer
2 transparent transmission is shut off avoiding producing unidirectional unwanted data
stream.
