Which of the following commands can be run on R3 to delete the redundant RTs without affecting the connectivity between all devices and the NMS?

Options:
A. undo vpn-target 3:1 import-extcommunity
B. undo vpn-target 1:3 export-extcommunity
C. undo vpn-target 1:3 import-extcommunity
D. undo vpn-target 2:3 export-extcommunity
Question 2
On the OSPFv3 network shown in the figure, the IPv6 address of Loopback0 on R3 is 2000-3/128, and OSPFv3 is enabled. Which of the following statements are true?

A. The Link-LSA generated by R2 does not exist in the LSDB of Rl.
B. Rl definitely generates a Network-LSA.
