VPRN Features

Spoke SDPs

Distributed services use service distribution points (SDPs) to direct traffic to another SR-Series

router via service tunnels. SDPs are created on each participating SR-Series and then bound to a

specific service. SDP can be created as either GRE or MPLS. Refer to

(SDPs) on page 46

This feature provides the ability to cross-connect traffic entering on a spoke SDP, used for Layer 2

services (VLLs or VPLS), on to an IES or VPRN service. From a logical point of view, the spoke

SDP entering on a network port is cross-connected to the Layer 3 service as if it entered by a

service SAP. The main exception to this is traffic entering the Layer 3 service by a spoke SDP is

handled with network QoS policies not access QoS policies.

T-LDP status signaling and PW active/standby signaling capabilities are supported on ipipe and

epipe spoke SDPs.
