The VLANs’ bridging paths 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
NOTE: The configurations in this chapter are only partial examples of
complete and functional router configurations. Do not copy these
configurations and use them directly on an actual system.
The following is the configuration of interfaces, virtual switches, and bridge domains for
MX Series router L2-PE1:
