Mapping RSVP Tunnel Name to L2VPN Service

This chapter shows configurations of mapping of rsvp tunnel-name to L2VPN service.

An MPLS Layer 2 Virtual Circuit (VC) is a point-to-point Layer 2 connection transported via MPLS on the service provider's network. The Layer 2 circuit is transported over a single Label Switched Path (LSP) tunnel between two Provider Edge (PE) routers

Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint-to-multipoint communication over IP- MPLS networks. It allows geographically-dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires. A set of Martini circuits is grouped by a common VPLS identifier to achieve this service objective.

Topology

This topology will be applicable for both VPWS and VPLS services.

Configuring the Virtual Circuit (VC)

Loopback addresses being used should be advertised through OSPF, or should be statically routed.

1.

Configure the IP address and OSPF for the PE1, P (Provider), and PE2 routers.

2.

Configure MPLS and LDP on PE1, P, and PE2, and LDP targeted peer for the PE1 and PE2 routers. (If RSVP is used for configuring trunks, LDP must be configured on PE1 and PE2, and RSVP must be configured on PE1, P, and PE2).

3.

Configure the VC with trunk-name.

4.

Bind the customer interface to the VC.
