no ip address
vrf forwarding BLUE - B . interface GigabitEthernet2
no vrf forwarding RED
vrf forwarding BLUE
ip address 10.0.0.0 255.255.255.254 - C . interface GigabitEthernet2
no vrf forwarding RED
vrf forwarding BLUE - D . interface GigabitEthernet2
no ip address
ip address 10.0.0.0 255.255.255.254
vrf forwarding BLUE

Which action advertises R2 loopback back into the R3 routing table?
- A . Add a static route for R2 loopback address in R1 and redistribute it to advertise to R3.
- B . Use a leak map on R1 that matches the required prefix and apply it with the distribute list command toward R3.
- C . Use a leak map on R3 that matches the required prefix and apply it with the EIGRP stub feature.
- D . Add a static null route for R2 loopback address in R1 and redistribute it to advertise to R3.
Refer to the exhibit.
