Example for Configuring MVPNv6 over BIERv6 on an L3VPNv6 over SRv6 Network
This section describes how to configure MVPNv6 over BIERv6 on a unicast L3VPNv6 over SRv6 network.
Networking Requirements
In Figure 1, L3VPNv6 over SRv6 has been deployed. It is required that MVPNv6 over BIERv6 be deployed on the existing network.
Configuration Roadmap
The configuration roadmap is as follows:
(Optional) Configure L3VPNv6 over SRv6 and ensure that the unicast VPN runs properly. If the unicast network has been configured, skip this step.
Configure basic BIERv6 functions and enable IS-ISv6 for BIERv6 on PE1, PE2, PE3, and the P.
Establish BGP MVPN peer relationships between PEs.
- Configure multicast traffic forwarding over a BIERv6 I-PMSI tunnel.
- Enable the BIERv6 S-PMSI tunnel function and configure switching criteria.
Enable PIM on PEs.
Data Preparation
To complete the configuration, you need the following data:
- IP addresses of key interfaces on each device, as shown in Figure 1
- ID (1) of the public network IS-IS process, in a Level-2 area
- VPN instance name (VPNA) on PE1, PE2, and PE3
- PE2's BFR-ID (2), PE3's BFR-ID (3), sub-domain ID (0), BSL (256), and Max-SI (0)
Procedure
- (Optional) Configure L3VPNv6 over SRv6.
This step is a part of configuring the unicast network, and its content is for reference only. In most cases, the unicast network has been configured before multicast services are deployed. If this is the case, skip this step and contact the configuration personnel for the configuration data related to the multicast services. For details about how to configure a unicast network, see Segment Routing IPv6 Configuration in the Configuration Guide.
# Enable IPv6 forwarding on each interface and assign an IPv6 address for each interface. The configuration of PE1 is used as an example. The configurations of PE2, PE3, and the P are similar to the configuration of PE1. For configuration details, see Configuration Files in this section. Similar details will be omitted in the rest of the document.
