[j-nsp] equal-cost, multi-next-hop static routes

[Joe Abley]

A router of my acquaintance in Toronto has:

jabley at agg01.tor-Switch> show version | grep Base
JUNOS Base OS boot [8.5R4.3]
JUNOS Base OS Software Suite [8.5R4.3]

jabley at agg01.tor-Switch>

and also

routing-options {
     static {
         route 69.165.166.240/28 next-hop [ 69.165.167.156  
69.165.167.20 ];
     }
     forwarding-table {
         export load-balancing-policy;
     }
}
policy-options {
     policy-statement load-balancing-policy {
         then {
             load-balance per-packet;
         }
     }
}

The idea is to do some crude load-sharing of outbound traffic from  
this router towards 69.165.166.240/28. Both 69.165.167.156  
69.165.167.20 are reachable via interface/connected routes.

The router only ever seems to select one next-hop. Interface counters  
elsewhere confirm that only one path is being used for traffic towards  
the customer.
