Note the use of the vlan-id all and vlan-id-range statements in the VPLS instance called
customer-c1-v1-to-v1000. The vlan-id all statement implicitly creates multiple learning
domains, each with its own normalized VLAN.
The following happens as a result of the vlan-id all configuration:
•
Packets received on logical interfaces ge-1/0/0.1 , or ge-2/0/0.1, or ge-3/0/0.1, with a
single VLAN tag in the range from 1 through 1000 in the frame are accepted.
•
Unknown source MAC addresses and unknown destination MAC addresses are learned
based on their normalized VLAN values of 1 through 1000.
•
All packets sent on the VPLS pseudowire have a normalized VLAN tag after the source
MAC address field in the encapsulated Ethernet packet.
•
Although there are only three logical interfaces in the VPLS instance called
customer-c1-v1-to-v1000, the same MAC address (for example, M1) can be learned on
different logical interfaces for different VLANs. For example, MAC address M1 could
be learned on logical interface ge-1/0/0.1 for VLAN 500 and also on logical interface
ge-2/0/0.1 for VLAN 600.
