Example for Configuring eMDI Detection for NG MVPN over BIER Services

This section provides an example for configuring eMDI detection for NG MVPN over BIER services.

Networking Requirements

On the network shown in Figure 1, next-generation multicast VPN (NG MVPN) over BIER services is deployed to resolve multicast service traffic congestion, reliability, and security issues on the carrier's backbone network. In addition, BIER eMDI is deployed on the root, P, Leaf1, and Leaf2 nodes to detect the quality of multicast services. Network maintenance personnel can view the real-time detection results reported through telemetry on the monitor platform and quickly demarcate and locate network faults based on the detection results.

Figure 1 NG MVPN over BIER networking

Interfaces 1 and 2 in this example represent GE 0/1/0 and GE 0/1/1, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure NG MVPN over BIER.
Configure BIER eMDI detection on the root node.
1. Configure a channel group for BIER eMDI.
2. Configure a board group for BIER eMDI.
3. Bind the channel group to the board group.
Configure BIER eMDI on P, Leaf 1, and Leaf 2.
1. Configure a board group for BIER eMDI.
2. Bind the channel group to the board group.
Configure telemetry.

Data Preparation

To complete the configuration, you need the following data:

IP addresses of interfaces (shown in Figure 1)
Multicast group address: 225.1.1.1/24
Multicast source address: 192.168.0.100/24
Name of a multicast VPN instance: VPNA
ID of a BIER sub-domain: 0
BIER BSL: 256
Name of the channel group for BIER eMDI: BIER-channel
Name of the board group for BIER eMDI: BIER-lpu

Procedure

Configure NG MVPN over BIER. For common configuration details, see Configuring NG MVPN over BIER. For configuration details in this example, see Configuration Files.

Configure a channel group for BIER eMDI.

A channel group for BIER eMDI is required only on the root node.

[~Root] emdi
[~Root-emdi] emdi channel-group BIER-channel
[*Root-emdi-channel-group-BIER-channel] emdi channel 1 source 192.168.0.100 group 225.1.1.1 vpn-instance VPNA sub-domain 0 bsl 256
[*Root-emdi-channel-group-BIER-channel] quit
[*Root-emdi] quit
[*Root] commit

Configure a board group for BIER eMDI.
The configurations of the root, P, Leaf1, and Leaf2 nodes are similar. The following uses the root node as an example. For detailed configurations of other nodes, see Configuration Files.
```
[~Root] emdi
[~Root-emdi] emdi lpu-group BIER-lpu
[*Root-emdi-lpu-group-BIER-lpu] emdi bind slot all
[*Root-emdi-lpu-group-BIER-lpu] quit
[*Root-emdi] quit
[*Root] commit
```
Bind the channel group to the board group.
The configurations of the root, P, Leaf1, and Leaf2 nodes are similar. The following uses the root node as an example. For detailed configurations of other nodes, see Configuration Files.
```
[~Root] emdi
[~Root-emdi] emdi bier bind lpu-group BIER-lpu
[*Root-emdi] quit
[*Root] commit
```

After the preceding configurations are complete, run the display emdi statistics history bier channel command to query the detection result when BIER packets are forwarded by the detected device. The following uses the P node as an example to describe how to query the detection result of outgoing traffic on the P node.

Configure telemetry.

The configurations of the root, P, Leaf1, and Leaf2 nodes are similar. The following uses the root node as an example. For detailed configurations of other nodes, see Configuration Files.

Configure a destination collector.

[~Root] telemetry
[*Root-telemetry] destination-group Monitor
[*Root-telemetry-destination-group-Monitor] ipv4-address 10.1.7.2 port 10001 protocol grpc no-tls
[*Root-telemetry-destination-group-Monitor] commit
[~Root-telemetry-destination-group-Monitor] quit

Configure sampling paths.

[~Root-telemetry] sensor-group emdimonitor
[*Root-telemetry-sensor-group-emdimonitor] sensor-path huawei-emdi:emdi/bier-out-telem-reps/bier-out-telem-rep
[*Root-telemetry-sensor-group-emdimonitor] sensor-path huawei-emdi:emdi/bier-out-telem-rtps/bier-out-telem-rtp
[*Root-telemetry-sensor-group-emdimonitor] commit
[~Root-telemetry-sensor-group-emdimonitor] quit

Create a static subscription.

[~Root-telemetry] subscription EMDI
[*Root-telemetry-subscription-EMDI] sensor-group emdimonitor
[*Root-telemetry-subscription-EMDI] destination-group Monitor
[*Root-telemetry-subscription-EMDI] commit

After completing the configuration, check the BIER eMDI detection result reported through telemetry on the monitor platform.
