Services Applications

  • Support for MAP-T solution (MX Series)—Starting in Junos OS Release 23.4R1, you can configure Mapping of Address and Port using Translation (MAP-T) as an inline service on MX Series routers with MPCs and MICs. MAP-T is a double stateless NAT64-based solution. The MAP-T solution uses IPv4-IPv6 translation as the form of IPv6 domain transport. The translation mode is considered advantageous in scenarios where the encapsulation overhead or IPv6 operational practices rule out encapsulation.

  • Support for consistent hash load balancing on FTIs (MX Series)—

    Starting in Junos OS Release 23.4R1, flexible tunnel interfaces support consistent hash load balancing on the MX Series routers. During load balancing, when the number of ECMP paths crosses the threshold, the server fails and results in traffic skewness.

    With consistent hashing, you can avoid skewness of the flows toward initial set of ECMP paths. Only the flows for paths that are inactive are redirected. Flows mapped to servers that remain active are maintained.

  • Enhancement to IP-IP tunnel configuration (SRX300, SRX320, SRX340, SRX345), SRX380)—Starting in Junos OS Release 23.4R1, when you configure an IP tunnel (ip-x/y/z) on the listed firewall devices at the [edit interfaces interface-name unit unit-number tunnel] hierarchy level, you can also configure:

    • Interface for tunnel source

    • Hostname for tunnel source

    • Hostname for tunnel destination

    • Tunnel encapsulation type
