Supported MPLS Scaling Values
This topic lists the MPLS scaling values supported on the QFX Series and EX4600 switches.
Table 1 lists the MPLS scaling values supported on the QFX3500, QFX5100, QFX5110, QFX5120, QFX5200, QFX5210, EX4600, and EX4650 switches.
Starting in Junos OS Release 19.1R1, the ingress tunnel scale is enhanced on QFX Series switches. For instance, you can increase the scale from its default 1024 to 2048 on QFX5100 switches. This enhancement optimizes and increases the ingress tunnel scale to address the needs of data center networks either in IP-CLOS or IP over MPLS application spaces.
