1.1 Overview
1.1.1 Introduction to MPLS Hybrid Insertion
For S9500 series routing switches, only the interface cards with suffixes C, CA and CB
and VPLS service processor cards support MPLS function. If you want to enable MPLS
VPN function of S9500 switches, you need MPLS-supporting interface cards or VPLS
service processor cards. The MPLS hybrid insertion feature is used to enable
deployment of MPLS VPN services on cards that do not support MPLS. S9500 routing
switches support various modes of MPLS VPN function and provide abundant and
differentiated MPLS VPN service to meet the differentiated needs of different users in
the performance, reliability, port utilization of MPLS VPN functions.
Note:
Unless otherwise specified, MPLS VPN services are processed by the
MPLS-supporting interface cards. In this manual, an interface card that supports
MPLS function is called MPLS card for short, and an interface card that does not
support MPLS function is called non-MPLS card for short.
The purpose of MPLS hybrid insertion is to enable the non-MPLS cards to support
MPLS function through the MPLS cards. Refer to the VPN section in this manual for
the information on the processing of MPLS VPN through VPLS service processor
cards.
1.1.2 MPLS Hybrid Insertion Mechanism
The implementation mechanism for MPLS hybrid insertion is as follows.
The MPLS card and the non-MPLS card co-exist in the same switch;
