Routing Protocols
-
Support for DDoS IS-IS classification (MX Series with MPCs MPC1 through MPC9, PTX1000, PTX5000, PTX10002, PTX10008, QFX10002, QFX10002-60C, QFX10008, and QFX10016)—Starting in Junos OS Release 22.1R1, Junos OS classifies IS-IS hello packets and IS-IS data packets separately. You can apply different policers to different types of IS-IS packets to improve the performance of IS-IS during congestion so that IS-IS doesn’t go down when a large number of packets are entering the device.
Configure DDoS protection settings for IS-IS hello packets and IS-IS data packets separately using the
isis-hello
orisis-data
statement at the[edit system ddos-protection protocols isis]
hierarchy level. Use theshow ddos-protection protocols isis parameters brief
command to view the aggregate number of IS-IS packets as well as the number of IS-IS hello packets and IS-IS data packets.[See protocols (DDoS) (ACX Series, PTX Series, and QFX Series) and show ddos-protection protocols isis.]
-
Support for adaptive RSVP update threshold (cRPD, MX240, MX480, MX960, PTX1000, PTX10008, QFX10002-60C, and QFX10008)—Starting in Junos OS Release 22.1R1, you can configure the RSVP update threshold percentage and threshold value to adaptively pace IGP updates. You can configure a lower frequency when the adaptive bandwidth is higher and configure a higher frequency when the bandwidth is lower.
You can enable the threshold percentage by using the
update-threshold adaptive limit limit threshold-percent percentage
configuration, and threshold value by using theupdate-threshold adaptive limit limit threshold-value value configuration
at theedit protocols rsvp interface
hierarchy level.Note:You cannot configure both
threshold-percent
andthreshold-value
simultaneously on the same interface.[See update-threshold.]
-
Support for CBF fallback inside service group (MX10008)—Starting in Junos OS Release 22.1R1, you can create a
te-group-id id
group for uncolored tunnels. This helps to enable class-based forwarding (CBF) and fallback inside a service group at the same time for uncolored static segment routing–traffic engineering (SR-TE) label-switched paths (LSPs) with the first hop as a label or as an IP address.Note:Colored SR-TE LSPs do not support this feature.
