ALU 7750 SR Service Architecture

Alcatel-Lucent 7750SR Service model

Various service provider VPN technologies (L2 and L3 VPN) are supported in 7750SR. Alcatel-Lucent's view of implementing these technologies are well structured in a model. Here I will describe the components of this model with sample configuration.

Components

1. Customer: Every service will be associated with a customer ID, which has no real effect on the router functions. Its mainly used for reporting purpose.
2. Service: Any VPN service (VPWS, VPLS, VPRN) should have an ID and must be associated with a customer.
3. SAP: Service access point (SAP) is simply the interfaces facing the customer devices
4. SDP: Service distribution point (SDP) is the logical interface representing the transport tunnel towards other PEs. It actually establishes a T-LDP.

Configuration Example

##### Creation of a customer #####

*A:PE-1# configure service customer 111 create
*A:PE-1>config>service>cust$ description "Customer ABC"
*A:PE-1>config>service>cust$ phone "+1-222-555-6666"

##### Configuration of SDP #####

*A:PE-1# configure service sdp 2 mpls create
*A:PE-1>config>service>sdp$ far-end 10.10.10.2
*A:PE-1>config>service>sdp$ ldp

#### Creation of an epipe/vpws service ####

*A:PE-1# configure service epipe 55 customer 111 create
*A:PE-1>config>service>epipe$ sap 1/1/2 create
*A:PE-1>config>service>epipe>sap$ exit
*A:PE-1>config>service>epipe# spoke-sdp 2:55 create
*A:PE-1>config>service>epipe>spoke-sdp$ exit
*A:PE-1>config>service>sdp$ no shutdown
