    Hi guys,

     

    I've found some log messages:

     

    rpd[16333]: mpls_label_alloc_mode_new FALSE
    rpd[16333]: INFO: krt mode is 1
    rpd[16333]: JUNOS ASYNC private vectors set
    rpd[16333]: INFO: krt nexthops_ptr set to ASYNC Mode

     

    I find no infomation about them, hoping someone can help me.

    Hi

     

    It seems like this error might have been seen after a commit operation related to rpd.

    Please check if at the time of log there was some mpls related routing change done.

     

     

    Hope this helps.

    Hi n2t. 

     

    Greetings, 

     

    rpd[16333]: mpls_label_alloc_mode_new FALSE
    rpd[16333]: INFO: krt mode is 1
    rpd[16333]: JUNOS ASYNC private vectors set
    rpd[16333]: INFO: krt nexthops_ptr set to ASYNC Mode >> Indicating KRT transitioning to asynchronous mode

     

    • As per my understanding, I believe you observed these logs when there was some commit performed.
    • During the commit, the KRT goes to asynchronous mode. It's an optimization to avoid blocking RPD process when it sends updates to the kernel. 
    • This is informational level and can be safely ignored.

     

    Hope this helps.
