Junos OS Release Notes for MX Series 3D Universal Edge Routers and T Series Core Routers

These release notes accompany Junos OS Release 15.1F6 for the MX Series and T Series. They describe new and changed features, limitations, and known and resolved problems in the hardware and software.

You can also find these release notes on the Juniper Networks Junos OS Documentation webpage, located at http://www.juniper.net/techpubs/software/junos/.

Caution: This release introduces some behavior changes to the unified in-service software upgrade (ISSU) functionality for MX Series and T Series routers. We do not recommend using unified ISSU to upgrade from an earlier Junos OS release to Junos OS Release 15.1.

Note: The following T Series routers are not supported in 15.1F6:

  • T320
  • T640
