NOTE: This is not a complete router configuration.
Consider the first VLAN for customer C1. The
called sets the normalized VLAN to 100. All packets sent over the
customer-c1-vsi
pseudowires have a VLAN tag of 100.
The following happens on VLAN 100 as a result of this configuration:
Packets received on logical interfaces
of 100 in the frame are accepted.
Packets received on logical interface
frame are accepted and have their tag values translated to the normalized VLAN tag
value of 100.
Unknown source MAC addresses and unknown destination MAC addresses are learned
based on their normalized VLAN values of 100.
All packets sent on the VPLS pseudowire have
Now consider the second VLAN for Customer C2. The
instance called
customer-c2-vsi
are sent over the VPLS pseudowires.
The following happens on the C2 VLAN as a result of the
A MAC table is created for each instance of
over the interfaces belonging to this VPLS instance are added to this table. The received
or configured VLAN tags are not considered when the MAC addresses are added to
this table. This is a case of shared VLAN learning.
Packets with a single VLAN tag value of 301 are accepted on interface
VLAN tag value 301 is then popped and removed from the frame of this packet.
