R1 is connected to both R2 and R3 and you want to load-balance outbound traffic. You have
provided the configuration shown in the exhibit; however, after checking the links you notice that
the traffic is not load-balancing.
Which configuration must be added?
A.
set protocols bgp group external multihop
B.
set protocols bgp group external multipath
C.
set protocols bgp group external advertise-external
D.
set policy-options policy-statement loadbal then accept
B is right

Step-by-Step Procedure
The following example requires that you navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure the BGP peer sessions:
Configure the BGP group.
[edit protocols bgp group external]
user@R1# set type external
user@R1# set peer-as 65001
user@R1# set neighbor 10.0.1.1
user@R1# set neighbor 10.0.0.2
Enable the BGP group to use multiple paths.
Note: To disable the default check requiring that paths accepted by BGP multipath must have the same neighboring autonomous system (AS), include the multiple-as option.
[edit protocols bgp group external]
user@R1# set multipath
Configure the load-balancing policy.
[edit policy-options policy-statement loadbal]
user@R1# set from route-filter 10.0.0.0/16 orlonger
user@R1# set then load-balance per-packet
Apply the load-balancing policy.
[edit routing-options]
user@R1# set forwarding-table export loadbal
Configure the local autonomous system (AS) number.
[edit routing-options]
user@R1# set autonomous-system 65000
