Routing Protocols

  • BMP local RIB monitoring support for all RIBs with sharding (ACX Series, cRPD, PTX Series, QFX Series, and vRR)—Starting in Junos OS Release 22.4R1, you can configure a policy to monitor routing information bases also known as routing table (RIBs) of virtual routers and virtual routing and forwarding instances (VRF). You can specify two separate sets of RIBs in the BGP Monitoring Protocol (BMP), one for monitoring and the other for reporting. With this feature, BMP can filter traffic based on the routes and routing instances.

    [See BGP Monitoring Protocol, loc-rib, and rib-list.]

  • MD5 authentication key rotation with overlap for key transition for OSPF (MX204, MX480, MX10003, PTX1000, and QFX10002)—Starting in Junos OS Release 22.4R1, we support advertising OSPF MD5 authentication with multiple active keys to send packets with a maximum limit of two keys per interface. Having multiple keys active at any one time at the interface enables the smooth transition from one key to another for OSPF. You can delete old keys without any impact on the OSPF session.

  • OSPF FAPM and interarea support (ACX5448, MX204, MX240, MX480, MX960, MX10003, MX10008, MX2008, MX2010, MX2020, PTX1000, and QFX10002)—Starting with Junos OS Release 22.4R1, the Flexible Algorithm Prefix Metric (FAPM) is defined to allow an optimal end-to-end path for an inter-area prefix. The Area Border Router (ABR) must include the FAPM when advertising the prefix between areas that areas reachable in that given Flex-Algorithm. When a prefix is unreachable, the ABR must not include that prefix in the Flex-Algorithm when advertising between areas. The defined FAPM provides inter-area support.

  • Support for bootstrapping route-validation database from a local file (cRPD, JRR200, MX204, PTX10008, and QFX10008)—Starting in Junos OS Release 22.4R1, we support the ability to read validation records from a local binary file and install into the specified named route-validation databases within RPD. This feature implements syntactic and semantic checks on the content of the file to ensure that it is a well-specified set of validation records. If the syntactic and semantic checks fail, the entire file is rejected as a source of validation records. Use the source-file statement at the [edit routing-options validation] hierarchy level to source route-validation records from a local file source. You can use the show validation source-file command to display the properties of a local validation source file.

  • MVPN feature support with sharding (cRPD, JRR200, MX2020, PTX5000, and QFX10002)—Starting in Junos OS Release 22.4R1, we support the following features:

    • Multicast virtual private network (MVPN) inactive route query from the main thread to shards

    • Extranet and auto-export support with sharding

    • Interact functions with RT-proxy client and server

    • New data structure to store the inactive route data on the main thread

    • Asynchronous route processing on the main thread

    You can use show mvpn c-multicast to display the inactive route data stored on the main thread.
