I need to pass through GVRP packets through a EX4600 switch which doesn't support GVRP. The switch is connected between two other switches that support and use GVRP. The EX4600 is dropping the GVRP multicast packets by default
Greetings, correct as you said GRVP is not supported only MVRP hence In this case, I would configure a Q-in-Q tunnel between both EX's and have them encapsulate the GRVP PDU's and forward them between the switches that are GRVP capable.
Here is how you can configure a Q-in-Q tunnel on an EX4600
I wanted to add more information about legacy GVRP standard protocol EEE 802.1ak.
GVRP is only supported on EX4200/ EX4500./ EX8200 / EX9200.
MVRP is an application protocol of the Multiple Registration Protocol (MRP) and is defined in the IEEE 802.1ak standard. MRP and MVRP replace Generic Attribute Registration Protocol (GARP) and GARP VLAN Registration Protocol (GVRP) and overcome GARP and GVRP limitations. [supporter by ELS devices, EX4600]
This standard specifies protocols, procedures, and managed objects to support the Multiple Registration Protocol (MRP). MRP allows participants in an MRP Application to register attributes with other participants in a Bridged LAN, Two Applications are defined, to register VLANs (MVRP) and Group MAC addresses (MMRP). MVRP will furthermore provide for the rapid healing of network failures without interrupting services to unaffected VLANs.
If the above info resolves your issue please mark as solved to help others!
You are welcome 🙂 It should if the rest of your devices are QinQ capable and also are able to process and decapsulate tunneled layer 2 protocols in your case GVRP, for example, if you use this EX4600 as a PE ( provider edge) this will encapsulate the GVRP and send it to the remote PE, if your remote PE is a CISCO device, here you can see how it is accomplished on the CISCO side.
Note: In the example above the EX configuration is different from the one I shared before because it is a legacy device that does not use the ELS ( enhanced layer 2 software) as the EX4600's hence you can disregard the EX configuration from this example.
