I am running protocol ospf on my lab Router.I have a load balancing policy configured on the forwarding table on my Router. The detialed output for an external route seen in the routing table is as below.

 

admin@R6# run show route 172.30.63.1/32 detail 

inet.0: 56 destinations, 64 routes (56 active, 0 holddown, 0 hidden)
172.30.63.1/32 (1 entry, 1 announced)
        *OSPF   Preference: 150
                Next hop type: Router, Next hop index: 262149
                Address: 0x94e4280
                Next-hop reference count: 73
                Next hop: 172.16.0.29 via ge-0/0/4.123
                Next hop: 172.16.0.37 via ge-0/0/4.135, selected

                AS path: I

inet.3: 35 destinations, 42 routes (6 active, 0 holddown, 34 hidden)

The forwarding table is also showing 2 next hops installed in it for this external route.

 

admin@R6# run show route forwarding-table destination 172.30.63.1 
Routing table: default.inet
Internet:

                              172.16.0.37        ucst   626    13 ge-0/0/4.135

The Trace for this external route is as below.

admin@R6# run traceroute 172.30.63.1 no-resolve    
traceroute to 172.30.63.1 (172.30.63.1), 30 hops max, 40 byte packets
 1  172.16.0.29  14.933 ms  14.972 ms 172.16.0.37  19.948 ms
 2  172.16.0.21  19.811 ms 172.16.0.13  19.937 ms  20.364 ms
 3  172.30.63.1  24.715 ms  24.814 ms 172.16.0.10  25.117 ms

[edit]
admin@R6# run traceroute 172.30.63.1 no-resolve    
traceroute to 172.30.63.1 (172.30.63.1), 30 hops max, 40 byte packets
 1  172.16.0.37  14.973 ms 172.16.0.29  14.855 ms  14.969 ms
 2  172.16.0.21  20.138 ms  20.070 ms 172.16.0.13  19.780 ms
 3  172.16.0.10  25.012 ms 172.30.63.1  24.665 ms  25.152 ms

I am confused in the output of traceroute that why it is showing two next-hops in every line of trace for this route. In line 1 it is showing 172.16.0.37 as well as 172.16.0.29. Is it because of load-balancing configured on my router?? Can anyone explain in detail ?? The topology diagram is also attached.
