What’s Changed in Release 21.1R3

EVPN

  • Community information no longer included in VRF routing table— The QFX series switches will no longer include the inherited advertised route target communities, EVPN extended communities, or vxlan encapsulation communities for EVPN Type 2 and EVPN Type 5 routes when an IP host is added in the VRF routing table.

Interfaces and Chassis

  • When configuring multiple flexible tunnel interface (FTI) tunnels, the source and destination address pair needs to be unique only among the FTI tunnels of the same tunnel encapsulation type. Prior to this PR, the source and destination address pair had to be unique among all the FTI tunnels regardless of the tunnel encapsulation type.

Junos XML API and Scripting

  • Refreshing scripts from an HTTPS server requires a certificate (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—When you refresh a local commit, event, op, SNMP, or Juniper Extension Toolkit (JET) script from an HTTPS server, you must specify the certificate (Root CA or self-signed) that the device uses to validate the server's certificate, thus ensuring that the server is authentic. In earlier releases, when you refresh scripts from an HTTPS server, the device does not perform certificate validation.

    When you refresh a script using the request system scripts refresh-from operational mode command, include the cert-file option and specify the certificate path. Before you refresh a script using the set refresh or set refresh-from configuration mode command, first configure the cert-file statement under the hierarchy level where you configure the script. The certificate must be in Privacy-Enhanced Mail (PEM) format.

    [See request system scripts refresh-from and cert-file (Scripts).]

Layer 2 Features

  • Configurable EtherType values (QFX10016)—You can now customize the EtherType field values stored in the ternary content addressable memory (TCAM) tables. With this feature, you can define custom EtherType values in place of some of the default values in the TCAM table either for a specified FPC slot or for all currently active FPCs on the switch. Some EtherType values are reserved; you can’t change or reconfigure those values.
