High Availability

  • Support for OSPFv3 and IS-IS BFD sessions using IPv6 link-local addresses (MX240, MX480, MX960, MX2010, MX2020, and MX10008 devices with MPC10 and MPC11 line cards)—Starting in Junos OS 22.2R1, MPC10 and MPC11 line cards on your network devices support OSPFv3 and IS-IS BFD sessions that use IPv6 link-local addresses.

    [See Configuring BFD.]

  • Insert additional SPC3 in a multinode high availability (HA) setup (SRX5800, SRX5600, and SRX5400)—Starting in Junos OS Release 22.2R1, you can insert SRX5K-SPC3 cards on the SRX5000 line of devices in a multinode HA setup without interrupting traffic.

    You can use the new procedure to insert SPC3 cards when the setup has an encrypted inter-chassis link (ICL) or a non-encrypted ICL.

    In case of an encrypted ICL setup, use the new statement set chassis high-availability hardware-upgrade on both nodes before you add SPC3 cards.

    We've also updated the show chassis high availability information command output to include messages related to SPC3 installation.
