[j-nsp] Juniper ECMP Junos 7.5R2.8 not working

[Paolo Autore]

?
If the links in question are ethernet try clearing the arp database-- if not then try this--the first one does the load balancing based on layer 3 and 4 information the second one does it based on flows-- 
 
forwarding-options 
hash-key {
    family inet {
        layer-3;
        layer-4;
    }
}
or you can do---------------
forwarding-options 
load-balance {
    indexed-next-hop;
}
routing-options
forwarding-table {
    export load-balance;
}
policy-options policy-statement
load-balance
   term 1 {
    then {
        load-balance per-packet;
    }
}

I have a scenarion wherein i send traffic across two equal cost links connected to Juniper M320 with Junos 7.5R2.8. The traffic load balances with multiple flows across both the equal cost link ..but whenever i break one of the links all the traffic shifts to the other link, when the link is restored the 50% traffic previously shifted to the sec. link does not come back up on the restored link.

Does this mean that ECMP on junos 7.5R2.8 is broken ...????

Cheers
RN
