Alcatel-Lucent 7750 SR OS - Filter Policies; Qos Policies; CE to PE Routing Protocols; PE to PE Tunneling Mechanisms

VPRN Features
Page 872 7750 SR OS Services Guide
QoS Policies
When applied to 7750 SR VPRN services, service ingress QoS policies only create the unicast
queues defined in the policy. The multipoint queues are not created on the service.
With VPRN services, service egress QoS policies function as with other services where the class-
based queues are created as defined in the policy.
Note that both L2 or L3 criteria can be used in the QoS policies for traffic classification in an
VPRN.
ATM traffic descriptor profiles define the traffic contract in the forward direction (ingress) and the
traffic contract in the backward direction (egress).
Filter Policies
Only IP filter policies can be applied to VPRN services.
CE to PE Routing Protocols
The 7750 SR VPRN supports the following PE to CE routing protocols:
•BGP
•Static
•RIP
• OSPF
PE to PE Tunneling Mechanisms
The 7750 SR supports multiple mechanisms to provide transport tunnels for the forwarding of
traffic between PE routers within the 2547bis network.
The 7750 SR VPRN implementation supports the use of:
• RSVP-TE protocol to create tunnel LSP's between PE routers
• LDP protocol to create tunnel LSP's between PE routers
• GRE tunnels between PE routers.
