Configuration Example: Implementing MVRP

In the following example, a core device is attached to three edge devices. Each of the edge devices is attached to other edge devices or host stations. The effects of MVRP in this network depend on the devices where the feature is enabled.

MVRP Network

Note: Although some of the devices in these configuration examples do not have statically configured VLANs, this is not a requirement. You can assign statically configured VLANs to devices running MVRP whenever necessary.

In this configuration, the edge devices advertise their statically configured VLANs to the Core Device. The Core Device does not have any statically configured VLANs but learns the VLANs from the edge devices.

Enter the following commands on the Core Device to enable MVRP globally (allowing the device to participate in the protocol), enable MVRP on the specified range of ports, and configure the specified range of ports as MVRP point-to-point interfaces.

core-device(config)# mvrp enable
core-device(config)# interface ethernet 1/2/1 to 1/2/3
core-device(config-mif-1/2/1-1/2/3)# mvrp enable

core-device(config-mif-1/2/1-1/2/3)# mvrp point-to-point

Enter the following commands on Edge Devices A, B, and C to statically configure two port-based VLANs, enable MVRP globally on the device, enable MVRP on port 1/2/1, and configure port 1/2/1 as an MVRP point-to-point interface.

Edge Device A Configuration:

deviceA(config)# vlan 20
deviceA(config-vlan-20)# untagged ethernet 1/1/1
Added untagged port(s) ethe 1/1/1 to port-vlan 20.

deviceA(config)# vlan 40
deviceA(config-vlan-40)# untagged ethernet 1/1/2
Added untagged port(s) ethe 1/1/2 to port-vlan 40.

deviceA(config)# mvrp enable

deviceA(config)# interface ethernet 1/2/1
deviceA(config-if-e40000-1/2/1)# mvrp enable

deviceA(config-if-e40000-1/2/1)# mvrp point-to-point 
deviceA(config-if-e40000-1/2/1)# exit

Edge Device B Configuration:

deviceB(config)# vlan 20
deviceB(config-vlan-20)# untagged ethernet 1/1/1
Added untagged port(s) ethe 1/1/1 to port-vlan 20.

deviceB(config)# vlan 30
deviceB(config-vlan-30)# untagged ethernet 1/1/2
Added untagged port(s) ethe 1/1/2 to port-vlan 30.

deviceB(config)# mvrp enable

deviceB(config)# interface ethernet 1/2/1
deviceB(config-if-e40000-1/2/1)# mvrp enable

deviceB(config-if-e40000-1/2/1)# mvrp point-to-point 
deviceB(config-if-e40000-1/2/1)# exit

Edge Device C Configuration: 

deviceC(config)# vlan 30
deviceC(config-vlan-30)# untagged ethernet 1/1/1
Added untagged port(s) ethe 1/1/1 to port-vlan 30.

deviceC(config)# vlan 40
deviceC(config-vlan-40)# untagged ethernet 1/1/2
Added untagged port(s) ethe 1/1/2 to port-vlan 40.


deviceC(config)# mvrp enable

deviceC(config)# interface ethernet 1/2/1
deviceC(config-if-e40000-1/2/1)# mvrp enable

deviceC(config-if-e40000-1/2/1)# mvrp point-to-point 
deviceC(config-if-e40000-1/2/1)# exit
