Configuring the JUNOS Software to Support Tunnel Interfaces on MX Series Ethernet Services Routers

Because the MX Series routers do not support Tunnel Services PICs, you create tunnel interfaces on MX Series routers by including the following statements at the [edit chassis] hierarchy level:

[edit chassis]fpc slot-number {pic number {tunnel-services {bandwidth (1g | 10g);}}}

fpc slot-number is the slot number of the DPC, MPC, or MIC. On the MX80 router, the range is 0 through 1.On other MX series routers, if two SCBs are installed, the range is 0 through 11. If three SCBs are installed, the range is 0 through 5 and 7 through 11.

The pic number On MX80 routers, if the FPC is 0, the PIC number can only be 0. If the FPC is 1, the PIC range is 0 through 3. For all other MX series routers, the rrange is 0 through 3.

bandwidth (1g | 10g) is the amount of bandwidth to reserve for tunnel traffic on each Packet Forwarding Engine.

1g indicates that 1 Gbps of bandwidth is reserved for tunnel traffic.

10g indicates that 10 Gbps of bandwidth is reserved for tunnel traffic.

If you specify a bandwidth that is not compatible, tunnel services are not activated. For example, you cannot specify a bandwidth of 1 Gbps for a Packet Forwarding Engine on a 10-Gigabit Ethernet 4-port DPC.

To verify that the tunnel interfaces have been created, issue the show interfaces terse operational mode command. For more information, see the JUNOS Interfaces Command Reference.
