MVRP example
Set up a network comprised of MVRP aware switches (1 - 4) connected in a ring topology with end
device groups, A1, A2, B1, and B2 in 2 different VLANs, A and B. With STP enabled on the
switches, the ports connecting switch 1 to switch 4 are in the discarding state, helping prevent a
loop condition.
Figure 51: MVRP Example Network for VLAN Registration
In the MVRP example network, the LANs first send a Join request to the switches. The switch
enters the VLAN registration in the forwarding database for the port receiving the frames.
The switch then propagates the request to the other ports, and sends the request to the neighboring
LANs and switches. This process continues until the switches have registered the VLANs in the
forwarding database of the receive port.
To enable MVRP on the switches, use the following steps.
To enable the MVRP ports on switch 1, use the following commands. Substituting the appropriate
interfaces in the commands, enable the MVRP functions and ports on switches 2, 3 and 4.
