[j-nsp] SRX 650 reth interface load balancing

[Walaa Abdel razzak]

Hi Experts

 

I tried to verify load balancing on the reth interface for SRX 650
connected to logical router, but I can see that SRX always use one link
although we have two physical links between the router and the active
node and one link between the router and the passive node. I am pinging
directly from router to the FW. I need to load balance through the
active links. The configuration is as follows:

 

test at FW1# show interfaces reth0  

vlan-tagging;

redundant-ether-options {

    redundancy-group 1;

    lacp {

        active;

    }

}

unit 5 {

    description c1;

    vlan-id 5;

    family inet {

        address 172.16.0.2/30;

    }

}

 

ge-2/0/1 {

    gigether-options {

        redundant-parent reth0;

    }

}

ge-2/0/2 {

    gigether-options {

        redundant-parent reth0;

    }

}

ge-11/0/1 {

    gigether-options {

        redundant-parent reth0;

    }

}

And the load balance policy:

 

test at FW1# show routing-options 

forwarding-table {

    export ECMP;

}

 

test at FW1# show policy-options policy-statement ECMP 

term load-balance {

    then {

        load-balance per-packet;

    }

}
