    Hi,


    When changing from ip to enhanced-ip network-services,  on the below link, this is required: System reboot is required (PFE/FPCs)

    https://www.juniper.net/documentation/en_US/junos/topics/topic-map/chassis-guide-tm-config-ntwrk-srvics-mode.html

    Which is different than the other network-services changes, at least in term of words.

    As a matter of fact, what exactly is required when changed from ip to enhanced-ip? Full system reboot (all REs and FPCs in the same time) or we can reboot, one by one ?

    A reboot of the re and cards is required after the change.

    For minimum time I successfully used the following process

    • remove re redundancy configuration

    delete routing-options nonstop-routing 
    delete chassis redundancy graceful-switchover
    delete protocols layer2-control nonstop-bridging
    commit synchronize​
    • Make the mode change configuration and commit synchronize 
    • Prep system for upgrade by saving rescue config and snapshot
    • Upgrade backup RE1 & reboot backup RE1
    • Verify backup RE is in new forwarding mode
    in junos:
    show chassis network-services
    from shell:
    user@router> start shell
    % sysctl -a | grep netsvc
    net.netsvc: 2
    The variable net.netsvc can be one the following values:
     
    0 : IP
    1 : ethernet
    2 : enhanced IP
    3 : enhanced Ethernet
    4 : all IP
    5 : all Ethernet
    6 : enhanced mode
    7 : lan
    
    ​

    • Switch master to backup RE1 (this is where the cards reboot and downtime occurs)
    • Upgrade RE0 & reboot
    • Restore redundancy configuration
    • Confirm sync & redundancy is good then graceful switch back to RE0
    master
    show task replication
    
    backup
    show system switchover​

    • Update rescue & snapshot

    Entire system reboot ( both the REs and FPCs ) is required : request system reboot or request vmhost reboot ( for VM based systems ).

    Thank you all that answered.

    It does not look possible to avoid the disconnection of all the FPCs .


    Thanks.
