[j-nsp] M7i and equal cost static routes

Hi,

My upstream has Cisco router  and I have 2xSTM-1 connected with my Cisco
router. We have 2 equal cost static routes in loopback address in order
to load balance the traffic, I believe it is "per-destination" both
side. I want to replace my end Cisco router with M7i and below is my
interface and static routes config. Unfortunately I don't have any Cisco
router with STM interfaces to test.  As I don't want my upstream to make
any changes are there any thing I need to look at? I can only see
"per-packet" load balancing option in policy?  Do I need "multipath" in
bgp as well?

Current Cisco config:

interface POS1/0
 description 1st Link
 ip address 172.16.0.1 255.255.255.252

interface POS2/0
 description 2nd Link
 ip address 172.16.1.1 255.255.255.252

ip route 192.168.1.1 255.255.255.255 POS1/0
ip route 192.168.1.1 255.255.255.255 POS2/0

192.168.1.1 is my remote peer's loopback doing eBgp


My juniper config:

so-0/1/0 {
        description "1st Link ";
        encapsulation cisco-hdlc;
        sonet-options {
            no-payload-scrambler;
        }
        unit 0 {
            family inet {
                address 172.16.0.1/30;
            }
        }
so-0/1/1 {
        description "2nd Link ";
        encapsulation cisco-hdlc;
        sonet-options {
            no-payload-scrambler;
        }
        unit 0 {
            family inet {
                address 172.16.1.1/30;
            }
        }

routing-options {
    static {
        route 192.168.1.1/32 next-hop [ so-0/1/0.0 so-0/1/1.0 ];
