You are asked to share a customer’s routes between two separate Layer 3 VPNs. The VPNs must
remain separate. None of the shared routes should be sent to the remote PE devices.
Which two configuration elements are used to meet these requirements? (Choose two.)
A.
auto-export
B.
export-rib
C.
[edit policy-options policy-statement vpnb-export]
user@router# show
term 1 {
from {
protocol bgp;
interface ge-0/0/1.0;
}
then {
community add vpnb-target;
accept;
}
}
term 2 {
then reject;
}
D.
[edit policy-options policy-statement vpnb-export]
user@router# show
term 1 {
from {
protocol bgp;
interface ge-0/0/1.0;
}
then {
community add vpnb-target;
accept;

Explanation:
auto-export

Description
Export routes between routing instances.
This statement enables you to leak routes between VPN routing and forwarding (VRF) instances that are locally configured on a provider edge (PE) router. Auto export is always applied on the local PE router, because it applies to only local prefix leaking by evaluating the export policy of each VRF and determining which route targets can be leaked. The standard VRF import and export policies affect remote PE prefix leaking.
You can use this statement as an alternative to using the VRF import and export policies.
