MPLS Feature Support on QFX Series and EX4600 Switches

 

MPLS is a set of procedures for augmenting network layer packets with label stacks, thereby turning them into labeled packets. Service providers frequently use MPLS. Simply put, where routers in a traditional network each perform an IP lookup to determine the next hop, the first device in an an MPLS network does a routing lookup for the final destination instead of the next hop. A label is then applied to the packet—this is called packet switching. The final destination device removes the label.

A number of Juniper Networks switches are capable of running a subset of MPLS and can, therefore, communicate not only with each other, but with Juniper Networks routers running MPLS. This topic describes the major MPLS features that are supported on QFX Series and EX4600 switches. Be sure to check for any exceptions to this support in MPLS Limitations on QFX Series and EX4600 Switches.

Note

EX4600 switches use the same chipset as QFX5100 switches—this is why that EX Series switch is discussed here along with QFX Series switches. Other EX Series switches also support MPLS but with a different feature set.

This topic describes:

MPLS Commands Supported by QFX Series and EX4600 Switches

QFX Series and EX4600 switches support a subset of MPLS features. The CLI for switches displays all MPLS related configuration statements, even those that are not supported. However, configuring those unsupported statements on a switch has no effect on the operation of the switch.

MPLS Features Supported by QFX Series and EX4600 Switches

The tables in this section lists the major MPLS features supported on the QFX Series and EX4600 switches, and the Junos OS release in which they were introduced. Table 1 lists the features for the QFX10000 switches.Table 2 lists the features for the QFX3500, EX4600, EX4650, QFX5100, QFX5120, QFX5110, QFX5200, and QFX5210 switches.
