bandwidth (Tunnel Services)

Syntax

Hierarchy Level

Description

(ACX Series, MX Series 5G Universal Routing Platforms and T4000 Core Routers only) Configure the amount of bandwidth in gigabits per second reserved on each Packet Forwarding Engine for tunnel traffic using tunnel services. Configuring the bandwidth creates a virtual tunnel interface that is represented as lt-<fpc/pic/port>.

Options

bandwidth-value—Amount of bandwidth in Gbps to reserve for tunnel traffic using tunnel services:

  • On ACX Series routers, the bandwidth values can be 1g or 10g.

  • On MX Series routers, the bandwidth values can be as follows:

    • 1g

    • 10g through 100g in 10 Gbps increments: 10g, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, 100g

    • 100g through 400g in 100 Gbps increments: 100g, 200g, 300g, 400g

  • On T4000 routers, the bandwidth values can be 10g through 100g in 10 Gbps increments: 10g, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, 100g.

Note:

The bandwidth that you specify determines the port number of the tunnel interfaces that are created. When you specify a bandwidth of 1g, the port number is always 10. When you specify any other bandwidth, the port number is always 0.

Note:

If you specify a bandwidth that is not compatible with the type of DPCs or MPCs and their respective Packet Forwarding Engine, tunnel services are not activated. For example, you cannot specify 1 gigabit per second bandwidth for a Packet Forwarding Engine on a 10-Gigabit Ethernet 4-port DPC or 16x10GE 3D MPC.

When the tunnel bandwidth is unspecified in the Routing Engine CLI, the maximum tunnel bandwidth for MPC3E is 60G.
