  • Support for RSVP delay constraint (cRPD, MX960, and PTX10008)—Starting in Junos OS Release 22.2R1, you can configure RSVP label-switched paths (LSPs) to use a delay metric for computing the path. To configure, use the new CLI options that we've introduced under the [edit protocols mpls label-switched-path name] hierarchy. We've also updated the outputs of the following show commands:

    • show ted link detail
    • show ted database extensive
    • show route protocol bgp table lsdist.0 extensive
    • show spring-traffic-engineering lsp detail
    • show express-segments name name detail
    • show mpls lsp detail
  • Support for ingress and transit chained CNHs for BGP Labeled Unicast (BGP-LU) IPv4 (MX204, MX480, MX960, MX10003, and vMX)—Starting in Junos OS Release 22.2R1, you can configure the chained composite next hops (CNHs) for devices handling ingress or transit traffic in the network. We've added support only for the following options on the listed MX Series devices:

    • BGP-LU for IPv4 on the ingress router—set routing-options forwarding-table chained-composite-next-hop ingress labeled-bgp inet
    • BGP-LU on the transit router—set routing-options forwarding-table chained-composite-next-hop transit labeled-bgp

    You can also configure class of service (CoS) and define rewrite rules for ingress and transit chained CNHs for BGP-LU.


    This feature is supported only on MPC9 and the previous models of line cards.

  • Support for SD-WAN (SRX5000 line of devices)—Starting in Junos OS Release 22.2R1, we support MPLS-based SD-WAN deployments on SRX5000 devices at spoke and hub locations. You can configure the SRX5000 devices to permit or deny virtual routing and forwarding (VRF)-based traffic that enters the device from overlay tunnels. The support includes:
    • Networks with Layer 3 VPN

    • VRF instances
    • MPLS-based flow mode
    • MPLS-over-GRE and MPLS-over-IPsec tunnels
    • IPv4 and IPv6 traffic

    [See Configuring Security Policies for a VRF Routing Instance.]

  • CBF support for colored SR-TE (MX Series)— Starting in Junos OS 22.2R1 Release, you can create a multipath route between different transport tunnels in any inet6.3 RIBs to resolve service routes. We also support storage of transport-class in nexthop gateways, support preserve nh hierarchy for policy multipath, and extend cos policy to support transport-class color so that selective traffic can be steered over one of SR-TE or IGP flex-algo transport tunnels.

    To match transport-class key in FRR indirect keys structure, use transport-class color <color> at the [edit class-of-service forwarding-policy next-hop-map next-hop-map-name forwarding-class forwarding-class-name ] hierarchy level.

    To store a color value as FRR indirect keys structure for the leaked inet6.3 routes, use set best-effort color color at the [edit routing-options transport-class] hierarchy level.

    To enable expanded nh hierarchy support for policy-multipath routes for RIBs, use set preserve-nexthop-hierarchy at the [edit routing-options rib rib-name policy-multipath] hierarchy level. For any inet[6].3 RIBs, the preserve-nexthop-hierarchy is enabled by default.
