Documentation Updates

This section lists the errata and changes in Junos OS Release 15.1X53 for QFX10000 switch documentation.

Changes to Junos OS for QFX10000 Switches Documentation

MPLS

  • The new-feature item “Auto-bandwidth (QFX10000 switches)” has been removed from New and Changed Features in Junos OS Release 15.1X53-D60. The auto-bandwidth feature is supported starting with Release 15.1X53-D30 on QFX10000 switches.

Software Defined Networking (SDN)

  • For up-to-date information about configuring EVPN-VXLAN on QFX10000 switches, see Example: Configuring EVPN-VXLAN In a Collapsed IP Fabric Topology Within a Data Center.
  • The following updates will be added to the EVPN Control Plane and VXLAN Data Plane Feature Guide for QFX Series Switches:
    • QFX10000 switches that are deployed in an EVPN-VXLAN environment do not support an IPv6 physical underlay network.
    • In an EVPN-VXLAN environment, if you have manually configured a specific route target for each VNI by using the vrf-target statement in the [edit protocols evpn vni-options vni] hierarchy, you do not need to additionally configure the vrf-target statement with the auto option. The auto option automatically derives route targets for each VNI from the autonomous system (AS) that you specified by using the autonomous-system statement in the [edit routing-options] hierarchy.
    • In a topology in which EVPN-VXLAN is deployed over a two-layer IP fabric, a leaf device is multihomed to two QFX10000 switches, which function as spine devices. If the spine devices also function as redundant gateways, these devices must be configured with the same AS number that is specified in the autonomous-system statement in the [edit routing-options] hierarchy.
