Option: Configuring VPLS to Use LSI Interfaces

On M Series and T Series routers, VPLS uses tunnel-based PICs to create virtual ports on vt interfaces. If you do not have a tunnel-based PIC installed on your M Series or T Series router, you can still configure VPLS by using label-switched interfaces (LSIs) to support the virtual ports. Use of LSI interfaces requires the use of Ethernet-based PICs installed in an Enhanced FPC.

Note: On MX Series routers, when VPLS is used with an LSI interface for traffic flowing from the core to the egress CE, classification does not work on the egress PE.

To use LSI interfaces for VPLS instead of vt interfaces, include the no-tunnel-services statement at the [edit routing-instances instance-name protocols vpls] hierarchy level.

[edit routing-instances]instance-name {protocols {vpls {no-tunnel-services;}}}

Note: The following interface types do not support the use of LSI interfaces with VPLS:

  • Aggregated SONET/SDH interfaces (cannot be used as the core-facing interface)
  • Channelized interfaces (cannot be used as the core-facing interface)
  • ATM1 interfaces
