Routing Protocols

  • OSPF link delay measurement and advertising (PTX10001-36MR, PTX10004, and PTX10008)—Starting in Junos OS Evolved Release 22.1R1, you can measure and advertise various performance metrics in IP networks with scalability through probe messages that are sent by Two-Way Active Measurement Protocol (TWAMP) Light. OSPF receives probe messages and the measured values from TWAMP Light. OSPF advertises these messages as TLVs in packets. You can use these metrics to make path-selection decisions based on the network performance.

    [See How to Enable Link Delay Measurement and Advertising in OSPF.]

  • Support for DDoS IS-IS Classification and Higher DDoS Bandwidth for Layer 2 and Layer 3 protocols (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX100016)—Starting in Junos OS EVO Release 22.1R1, Junos OS EVO classifies IS-IS hello packets and IS-IS data packets separately and provides support for higher DDoS bandwidth for Layer 2 and Layer 3 protocols.

    [See show ddos-protection protocols isis and protocols (DDoS) (ACX Series, PTX Series, and QFX Series).]

  • BMP with BGP Sharding and Update IO (PTX10004, PTX10008, and PTX10016)— Starting in Junos OS Evolved Release 22.1R1, we support AdjOutRIBs (pre and post policy tables) through BGP Monitoring Protocol (BMP).
