Verifying That MVRP Is Working Correctly

Purpose

After configuring your MX Series router or EX Series switch to participate in Multiple VLAN Registration Protocol (MVRP), verify that the configuration is properly set and that MVRP messages are being sent and received on your switch.

Action

1. Confirm that the router is declaring Virtual LANs (VLANs).

   Show that MVRP is enabled:

   user@host> show mvrp

   MVRP configuration for routing instance 'default-switch'
   MVRP dynamic VLAN creation : Enabled
   MVRP BPDU MAC address      : Customer bridge group (01-80-C2-00-00-21)
   MVRP timers (ms)
     Interface       Join   Leave  LeaveAll
     ge-11/3/0        200     800     10000

   Show the MVRP applicant state:

   user@host> show mvrp applicant-state

   MVRP applicant state for routing instance 'default-switch'
    (VO) Very anxious observer, (VP) Very anxious passive, (VA) Very anxious new,
    (AN) Anxious new, (AA) Anxious active, (QA) Quiet active, (LA) Leaving active,
    (AO) Anxious observer, (QO) Quiet observer, (LO) Leaving observer,
    (AP) Anxious passive, (QP) Quiet passive
   
   VLAN Id     Interface          State
       100     ge-11/3/0          Declaring (QA)
       200     ge-11/3/0          Declaring (QA)
       300     ge-11/3/0          Declaring (QA)

2. Confirm that VLANs are registered on interfaces.

   List VLANs in the registered state:

   user@host> show mvrp registration-state

   MVRP registration state for routing instance 'default-switch'
   
   VLAN Id   Interface   Registrar   Forced      Managed    STP
                         State       State       State      State
       100   ge-11/3/0   Registered  Registered  Normal     Forwarding
       200   ge-11/3/0   Registered  Registered  Normal     Forwarding
       300   ge-11/3/0   Empty       Empty       Normal     Forwarding
   

3. Display a list of VLANs created dynamically.

   List dynamic VLAN membership:

   user@host> show mvrp dynamic-vlan-memberships

   MVRP dynamic vlans for routing instance 'default-switch'
    (s) static vlan, (f) fixed registration
   
   VLAN Id            Interfaces
       100            ge-3/3/0
                      ge-3/0/5
       200            ge-3/3/0
                      ge-3/0/5

Meaning

The output of show mvrp applicant-state shows that trunk interface ge-11/3/0 is declaring (sending out) interest in the VLAN IDs 100, 200, and 300 and MVRP is operating properly.

The output of show mvrp registrant-state shows the registrar state for VLANs 100 and 200 as Registered, indicating that these VLANs are receiving traffic from a customer site. VLAN 300 is in an Empty state and is not receiving traffic from a customer site.

The output of the show mvrp dynamic-vlan-membership shows that VLANs 100 and 200 are created dynamically (here, on an MX Series router operating as an aggregation switch between MX Series routers operating as edge switches). VLANs created statically are marked with an (s) (which is not indicated in this output).
