and P3, and Site 4 is connected to P1 and P3. VPLS pseudowires configured on the PE
and P routers carry traffic between the sites.

The pseudowires for the VPLS instances are shown with distinct dashed and dotted
lines. The VLANs at each site are:

L2-PE1 at Site 1: VLAN 100 and VLAN 300

L2-PE2 at Site 2: VLAN 100

L2-PE3 at Site 3: VLAN 100

L2-PE4 at Site 4: VLAN 300

Service provider SP-1 is providing VPLS services for customer C1 and C2. L2-PE1 is
configured with a VPLS instance called

customer-c1-vsi

. The VPLS instance sets up

pseudowires to remote Site 2 and Site 3. L2-PE1 is also configured with a VPLS instance
called

customer-c2-vsi

. The VPLS instance sets up a pseudowire to remote Site 4.

The following is the configuration of interfaces, virtual switches, and bridge domains for
MX Series router L2-PE1:
