Refer to the Exhibit.

A router is configured with the configuration shown in the exhibit. Traffic arriving on fe-0/0/0.0 is not being routed to 10.1.1.1.
What can you change to make the device route traffic arriving on fe-0/0/0.0 to 10.1.1.1?

A.
Add filter-based-forwarding enable to the configuration.

B.
Ensure that the to-10.1.1.1 routing instance has a route to 10.1.1.1.

C.
Add a from statement to the route-to-10.1.1.1 filter.

D.
Explicitly configure an interface in the default route in the to-10.1.1.1 routing instance.

Explanation:
Routing Instances Configuration Guidelines

You can create multiple instances of Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Label Distribution Protocol (LDP), Multicast Source Discovery Protocol (MSDP), Open Shortest Path First version 2 (OSPF), Open Shortest Path First version 3 (OSPFv3), Protocol Independent Multicast (PIM), Routing Information Protocol (RIP), and static routes by including statements at the following hierarchy levels:

* [edit routing-instances routing-instance-name protocols]
* [edit logical-systems logical-system-name routing-instances routing-instance-name protocols]

Note: The default routing instance, master, refers to the main inet.0 routing table. The master routing instance is reserved and cannot be specified as a routing instance.

Each routing instance consists of sets of the following:

* Routing tables
* Interfaces that belong to these routing tables
* Routing option configurations

You can configure eight types of routing instances:

* ForwardingUse this routing instance type for filter-based forwarding applications. For this instance type, there is no one-to-one mapping between an interface and a routing instance. All interfaces belong to the default instance inet.0.
* Layer2-control(MX-series routers only) Use this routing instance type for RSTP or MSTP in customer edge interfaces of a VPLS routing instance. This instance type cannot be used if the customer edge interface is multihomed to two provider edge interfaces. If the customer edge interface is multihomed to two provider edge interfaces, use the default BPDU tunneling.
* Layer2 VPNUse this routing instance type for Layer2 virtual private network (VPN) implementations.
* NonforwardingUse this routing instance type when a separation of routing table information is required. There is no corresponding forwarding table. All routes are installed into the default forwarding table. IS-IS instances are strictly nonforwarding instance types.
* Virtual routerSimilar to a VPN routing and forwarding instance type, but used for non-VPN-related applications. There are no virtual routing and forwarding (VRF) import, VRF export, VRF target, or route distinguisher requirements for this instance type.
* Virtual switch(MX-series routers only) Use the virtual switch instance type to isolate a LAN segment with its Spanning Tree Protocol (STP) instance and separates its VLAN identifier space. For more detail information about configuring a virtual switch, see the JUNOS MX-series Layer 2 Configuration Guide and the JUNOS MX-series Solutions Guide.
* VPLSUse the virtual private local-area network service (VPLS) routing instance type for point-to-multipoint LAN implementations between a set of sites in a VPN.
* VRFUse the VPN routing and forwarding routing (VRF) instance type for Layer3 VPN implementations. This routing instance type has a VPN routing table as well as a corresponding VPN forwarding table. For this instance type, there is a one-to-one mapping between an interface and a routing instance. Each VRF instance corresponds with a forwarding table. Routes on an interface go into the corresponding forwarding table.
