L2PT(MVRP) config issue on Q-in-Q

Hi, guys. 

 

I'm doing test about L2PT(specially, MVRP) on Q-in-Q. when smartbit keep sending vlan100 frame, the ge-0/0/23 is unplugged on sw3. However, I think when access port on vlan100 is unplugged, SW3 is send MRP messages to sw6

and then vlan100 traffic from sw2 will stop. 

but I captured broadcast and unknown unicast traffic on egress of ge-0/0/21. is there anyone who can check my configuration?

 

when I tested only MVRP not on Q-in-Q, it was good and operated well. 

 

I attached my topolgy and I'm sure that I made correct broadcast frame on smartbit. 

 

The following configurations are configuration of each SWs.

 

SW2

Re: L2PT(MVRP) config issue on Q-in-Q

If I'm reading that right, it looks as though you're doing mrvp within the q-in-q tunnel, and not using it at the outer trunking level?

Re: L2PT(MVRP) config issue on Q-in-Q

Dear,

 

I set trunk level on ge-0/0/21 of sw2 and ge-0/0/21 of sw3. cuz I understood that I have to set 'port-mode trunk'  when mvrp is set on that port.

Re: L2PT(MVRP) config issue on Q-in-Q

Okay. yeah. So vlan100's mvrp should transit between sw2 and sw3. The other switches in the middle shouldn't matter in this case. Which 0/0/21 port are you seeing the unknowns coming in on? Have you grabbed and analyzed them?
