    Dec 29 10:57:39 BRS-JN-1 (FPC Slot 0, PIC Slot 2) ms02 xntpd: NTP Server 128.0.0.1 is Unreachable

    FPC 0, PIC 2 its ms-mic-16g nat sercice card.

    Hello,

    I'd advise checking if any interface stuck in OVERLOAD STATE, from the output of " show services service-sets summary" 

    Otherwise, it seems that some NTP associations are not established correctly and you need to restart the NTP daemon or MS card to resolve the issue.

    128.0.0.1 is an internal IP address.  (do a show route all and you will see it) 

    Also, take a look at this document: https://kb.juniper.net/InfoCenter/index?page=content&id=KB11436

    You might need to configure 127.0.0.1/32 under the loopback interface or, if you have a firewall filter applied to the loopback, configure it to accept NTP traffic with SA = DA = your router's loopback interface.

    No, my ntp works correct, loopback, loopback filter etc, all correct, ntp synchronized. But what about 128.0.0.1? Its martian address and its not in my config,  and why I have get its message from fpc 0 pic 2, actually its my cgnat service card

    As I said the 128.0.0.1 is an internal IP address. You don't configure that. Those addresses are used internally for the router components to communicate. 


    ylara@R1> show route 128/8 all

    __juniper_private1__.inet.0: 7 destinations, 9 routes (7 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    128.0.0.1/32     *[Direct/0] 2d 04:37:39
                                         > via lo0.16385
    128.0.0.4/32     *[Direct/0] 2d 04:37:39
                                         > via lo0.16385
    128.0.0.6/32     *[Local/0] 2d 04:37:39
                                         Local via sp-0/0/0.16383
    128.0.1.16/32  *[Direct/0] 2d 04:37:39
                                         > via lo0.16385
                                        [Direct/0] 2d 04:37:39
                                         > via sp-0/0/0.16383

    I don't know about the log message. I would open a case with JTAC to find out. 

    Regards,
