  • 1.  Primary and backup link configuration on Juniper M7i router

    Posted 09-26-2011 03:10

    Hi,

     

          I have one Juniper M7i router and two internet link. I need configuration for backup link.

    If first link go down then second link should comes up automatic on the same router.

    Which protocol you are using on Internet links??

     

    In case of E-BGP you will any achieve the fail over once peering sessions are up..

    Hi Nikhil,

     

    You can use qualified-next-hop in this case as below:

     


    [edit]
    regress@huntington# show routing-options
    static {
        route 0.0.0.0/0 {
            next-hop 172.168.0.1;                        <<<< Primary Link
            qualified-next-hop 220.2.4.5 {               <<<< Backup Link
                preference 10;
            }
        }
    }

     

     

    Regards

    However in case of failover, you need to make the physical down in case of static routes...
