R0106-HP MSR Router Series MPLS Configuration Guide(V7)

306
Before configuring basic IPv6 MPLS L3VPN, complete the following tasks:
1. Configure an IGP on the PEs and P devices to ensure IP connectivity within the MPLS backbone.
2. Configure basic MPLS for the MPLS backbone.
3. Configure MPLS LDP on PEs and P devices to establish LDP LSPs.
Configuring VPN instances
By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes, but
also routes between VPNs. This feature allows VPN instances to be used in network scenarios besides
MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of its
associated site. A VPN instance does not necessarily correspond to one VPN.
To create and configure a VPN instance:

Command Remarks
1. Enter system view.
system-view N/A
2. Create a VPN instance and
enter VPN instance view.
ip vpn-instance vpn-instance-name
By default, no VPN instance is
created.
3. Configure an RD for the VPN
instance.
route-distinguisher
route-distinguisher
By default, no RD is specified.
4. (Optional.) Configure a
description for the VPN
instance.
description text
By default, no description is
configured for a VPN instance.
The description should contain the
VPN instance's related
information, such as its relationship
with a certain VPN.
5. (Optional.) Configure an ID for
the VPN instance.
vpn-id vpn-id
By default, no ID is configured for a
VPN instance.
6. (Optional.) Configure an
SNMP context for the VPN
instance.
snmp context-name context-name
By default, no SNMP context is
configured.
The following matrix shows the maximum number of VPN instances that can be created in the system:
Hardware Maximum value
MSR2000 1023
MSR3000 2047
MSR4000 4095
Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the interface connected
to the CE.
