This dissemination will result in the registration of this MAC on AS2, AS3, and AS4 and reachability
tree is formed. Similarly AS2, AS3 also declare for the flood MAC. AS4 will not declare because the
I-SID is not terminated on AS4. CS1 now has ports connecting to AS1, AS2, and AS3 registered to
the flood MAC for B-VLAN10. The

shows the reachability tree for the B-VLAN10.

When packets with this MAC address reach the CS, it will multicast only on ports on which
registration of the MAC address is present (for example: it will multicast to AS1, AS2 and AS3 but
not to AS4).

Unknown Unicast Multicasting in the above Topology:

1. AS2 is trying to send to a customer MAC C.

2. AS2 will flood the packet towards on port 2/1 the PBB network with the B-SA as the MS2 (Base

MAC of AS2) and B-DA as Multicast flood MAC, B-VLAN as 10 and ISID as 10000.

3. CS1 on receiving this packet will multicast to the ports on which it has registered the flood

MAC, in this case 1/2 and 1/10 (it will not send on 1/12 because of source port suppression).

4. If AS1 has been learnt the customer MAC C then it will strip the PBB header do Layer 2

forwarding towards the customer.

MMRP Operation Overview

MMRP defines an MRP application that provides the extended filtering services. MMRP makes use
of the following:

The declaration and propagation services offered by MAD and MRP to declare and propagate
Group membership, Group service requirement, and individual MAC address information
within the LAN
