  • 1.  lt-0/0/0 interface on SRX345 cluster

    Posted 07-26-2016 09:54

    Hello everyone.

     

    I'm configuring a new SRX345 cluster running 15.1X49-D50.3. 

     

    I'm trying to use an lt-0/0/0 interface so that I can bring up OSPF between my master routing instance and my MPLS routing instance. However, the lt-0/0/0 interface does not even show up when I do show interfaces terse. Any ideas as to what is going on here? Relevant config and show output is below.

    Just found this Juniper KB:

     

    https://kb.juniper.net/InfoCenter/index?page=content&id=KB28204&actp=RSS

     

    Quote, "As of Junos 12.1X45, logical tunnel (lt-0/0/0) interfaces are supported on Branch SRX platforms in Standalone mode, and are supported in high-end SRX devices in both Standalone and HA mode.

    The interfaces are not supported in SRX Branch devices in Cluster mode."

     

    Looks like they are STILL not supported on 15.1X49-D50.3. 

     

    Ugh. Smiley Frustrated

    Hi

     

    lt-interfaces are not supported in branch SRX clusters (they are only supported in standalone mode), see

    Hi,

     

    Just wandering if you need tunnel services enabled:

    [edit chassis]
    root@MX# show 
    fpc 0 { pic 0 { tunnel-services { bandwidth 1g; } } }

    Not sure if this is required on SRX.

    On MX if tunnel-services is not configured, lt interfaces do not show up:

    root@MX# run show interfaces terse lt-0/0/0 
    error: device lt-0/0/0 not found
    
    [edit]
    root@MX# commit 
    commit complete
    
    [edit]
    root@MX# run show interfaces terse lt-0/0/0 
    Interface               Admin Link Proto    Local                 Remote
    lt-0/0/0                up    up
    lt-0/0/0.0              up    up   inet     192.168.100.1/30
    lt-0/0/0.1              up    up   inet     192.168.100.2/30

    Cheers,

    Ashvin

    That configuration is not required on the SRX.  Pretty sure the issue is the lack of support for the feature in clusters on the SRX branch as noted above.
