Configure MPLS Parameter on IW URWB Mode Radios

Introduction

This document describes the configuration of MPLS parameters on IW9165 and IW9167 radios in URWB mode.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• Basic CLI navigation and commands
• Understanding of IW URWB mode radios

Components Used

The information in this document is based on these software and hardware versions:

• IW9165 and IW9167 radios
• Industrial Wireless service

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

MPLS is a routing technique that uses labels instead of IP addresses to send data from source to destination.

On IW9165 and IW9167 radios in URWB mode, several MPLS parameters can be configured via IoT OD with the Industrial Wireless service and CLI.

This document provides detailed instructions on configuring these parameters.

Configure

Current Configuration

To view the current MPLS configuration on the device:

device#show mpls configuration

Example output:

Configuration for MPLS:
- MPLS tunnels: Tunnel1, Tunnel2
- Unicast flooding: enabled
- Pseudowire formation: meshend
- Cluster ID: cluster1
- ARP limit: rate 100, grace 200, block 300
- ARP unicast flooding: enabled
- Reduce broadcast: enabled
- VBR table: 5 entries

Unicast Flooding

Step 1: Enable unicast flooding of MPLS packets.

device#configure mpls unicast enabled

Step 2: Disable unicast flooding of MPLS packets.

device#configure mpls unicast disabled

Step 3: Enable unicast flooding from non-private IP addresses.

device#configure mpls unicast restricted

Step 4: Enable retry limitations for unicast packets.

device#configure mpls unicast-flood rate-limit enabled

Step 5: Disable retry limitations for unicast packets.

device#configure mpls unicast-flood rate-limit disabled

Pseudowire Formation

Step 1: Enable pseudowires to only mesh end.

device#configure mpls pw-set meshend

Step 2: Enable pseudowires to all devices.

device#configure mpls pw-set all

Cluster ID

Step 1: Configure the cluster ID.

device#configure mpls cluster-id set cluster1

Step 2: Remove the cluster ID.

device#configure mpls cluster-id clear

ARP Limit

Step 1: Set the ARP limit rate.

device#configure mpls arp-limit rate N

Step 2: Set the ARP limit grace value.

device#configure mpls arp-limit grace rate X

Step 3: Set the ARP limit block value.

device#configure mpls arp-limit block Y

ARP Unicast Flooding

Step 1: Enable ARP unicast flooding.

device#configure mpls arp-unicast enabled

Step 2: Disable ARP unicast flooding.

device#configure mpls arp-unicast disabled

Reduce Broadcast

Step 1: Enable reducing broadcast packets.

device#configure mpls reduce-broadcast enabled

Step 2: Disable reducing broadcast packets.

device#configure mpls reduce-broadcast disabled

VBR Table

Step 1: Clear the VBR table from any device.

device#configure mpls vbr clear

Step 2: Add a new path to a device.

device#configure mpls vbr mac-list add <mac-address> <vlan id>

Step 3: Delete a learned path from the device.

device#configure mpls vbr mac-list clear <mac-address> <vlan id>

Verify

Step 1: Verify the MPLS configuration.

device#show mpls configuration

Explanation: This command displays the current MPLS settings and tunnels established on the device.

Step 2: Validate VBR table entries

device#show mpls vbr
