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
