Chapter 1 MPLS Hybrid Insertion Configuration
When configuring MPLS hybrid insertion, go to these sections for information you are
interested in:
z Overview of MPLS Hybrid Insertion
z Configuring Hybrid Insertion Based on LPUs with a Suffix of C, CA, or CB
z Configuring Hybrid Insertion Based on L3+ SPUs
z Hybrid Insertion Configuration Example
Note:
z For information about basic configuration of MPLS, refer to MPLS Basics
Configuration.
z MPLS hybrid insertion configuration does not involve the actual networking. It
simply demonstrates the MPLS processing capability, that is, a system that does not
support MPLS can provide MPLS/MPLS VPN services after configuration of MPLS
hybrid insertion.
z For detailed configuration information about service loopback group, ACL, and QoS,
refer to related manuals.
z A routing switch running MPLS has the functions of a router. The term "router” in this
document refers to a router in a generic sense or a Layer 3 Ethernet switch running
MPLS.
z For an S9500 Series routing switch, only line processor units (LPUs) with a suffix of
C, CA or CB and VPLS service processor cards (SPCs) support MPLS. For S9500
Series routing switches to support MPLS VPN functions, you need to equip them
with MPLS capable LPUs or VPLS SPCs. You can identify the suffix of an LPU by
the silkscreen in the upper right corner of the LPU’s front panel. As an example, the
silkscreen of an LSB1P4G8CA0 LPU is P4G8CA, and therefore the suffix of the
LPU is CA.
1.1 Overview of MPLS Hybrid Insertion
1.1.1 Introduction to Hybrid Insertion
Currently, the device supports both the SPUs with or without the MPLS function. In the
following description, these two types of SPUs are respectively referred to as MPLS
board and non-MPLS board. In order to provide the MPLS/MPLS VPN service in an
environment that does not support the MPLS, a lot of users require adding MPLS SPUs
Operation Manual – MPLS Hybrid Insertion
H3C S9500 Series Routing Switches Chapter 1 MPLS Hybrid Insertion Configuration
1-2
without changing the original networking. To meet this requirement, LPUs supporting
MPLS must be configured to redirect the MPLS service to the MPLS SPUs for service
processing. With the hybrid insertion feature, the MPLS VPN service can be deployed
on boards that do not support MPLS. The device supports the MPLS VPN in several
modes. It provides diversified MPLS VPN services to address different MPLS VPN
requirements, such as service performance, reliability, and port utilization ratio.
1.1.2 Classification of Hybrid Insertion
Although LPUs with a suffix of C, CA, or CB and L3+ SPUs support the MPLS function,
their functions and configurations are different. Accordingly, hybrid insertion is
classified into two types: hybrid insertion based on LPUs with a suffix of C, CA, or CB,
and hybrid insertion based on L3+ SPUs.
Here, MPLS hybrid insertion includes both L2VPN and L3VPN hybrid insertions.
I. Hybrid insertion based on LPUs with a suffix of C, CA, or CB
z Support hybrid insertion of LPUs with a suffix of C, CA, or CB and non-MPLS
SPUs.
z The service at the L3VPN private network side must be redirected to the MPLS
service loopback group on the MPLS board for processing.
II. Hybrid insertion based on L3+ SPUs
z Support hybrid insertion of L3+ SPUs and non-L3+ SPUs.
z VPLS service and MPLS packets with the outer label assigned by the public
network must be redirected to different virtual service interfaces on the L3+ SPUs
for processing.
1.2 Configuring Hybrid Insertion Based on LPUs with a Suffix
of C, CA, or CB
Before configuring hybrid insertion based on LPUs with a suffix C, CA, or CB, you need
to:
z Configure the MPLS service loopback group.
z Configure the QoS policy to redirect the private network packets to the MPLS
service loopback group in the case of L3VPN hybrid insertion.
1.2.1 Configuring Redirection of MPLS Service at Private Network Side
I. Configuration prerequisites
Before redirecting MPLS service at private network side, complete the following tasks:
z Configure the basic MPLS capability.
z Configure the service loopback group with the MPLS processing capability.

z Redirect the MPLS and VPLS services at the public network side to the virtual
service interface on the L3+ board for processing.
z Bind the VPLS instance with different MPLS-VPLS virtual service interfaces to
share the load of VPLS service.

interface on the L3+ board are used:
z MPLS virtual service interface
z MPLS-VPLS virtual service interface

Note:
z Currently, only MPLS boards with a suffix of CA or CB support VLL (L2VPN). Thus,
VLL hybrid insertion includes:
- Hybrid insertion of non-MPLS boards and MPLS boards with a suffix of CA
- Hybrid insertion of MPLS boards with a suffix of C and MPLS boards with a suffix of
CA
z All MPLS boards support MPLS L3VPN. Thus, L3VPN hybrid insertion refers to
hybrid insertion of non-MPLS boards and MPLS boards only.
z You need to configure the port-based QoS policy for L3VPN hybrid insertion only,
but not for VLL hybrid insertion.
1.4.3 Example for Configuring L3+ Hybrid Insertion
I. Network requirements
z Bind the VPLS virtual service interface with the VPLS instance.
z Configure the backup virtual service interface.
