Option: Configuring Tunnel Services on MX Series Routers

MX Series routers use Dense Port Concentrators (DPCs) with built-in physical ports, which means that you do not insert PICs on the router. Instead, you configure tunnel interfaces on one of the four Packet Forwarding Engines (PFEs) that are on each DPC.

To create tunnel interfaces on an MX Series router, include the tunnel-services statement at the [edit chassis fpc slot-number pic number] hierarchy level. To configure the bandwidth for a tunnel interface, include the bandwidth statement at the [edit chassis fpc slot-number pic number] hierarchy level.

The following example shows a tunnel interface with 1 Gbps of bandwidth configured on PFE 1 of the DPC installed in slot 4 of an MX Series router:

[edit chassis]fpc 4;pic 1 {tunnel services {bandwidth 1g;}}

Once you have configured a tunnel interface on a PFE, you can treat this interface as a standard tunnel interface and proceed with a standard VPLS configuration. For more information, see the JUNOS System Basics Configuration Guide.
