Refer to the exhibit. Company A has two sites, which are connected to PE1 and PE4 respectively. The route targets have been configured for the import and export values. PE1 and PE4 have established BG
The correct answer is A. Set the route-target import value on PE1 to 104:104. E. Set the route-target import values on PE4 to 101:101. In an L3VPN, reachability between sites depends on route-target import/export alignment. PE1 exports 101:101, and PE4 exports 104:104. For the two sites to learn each other’s routes, PE1 must import 104:104 (PE4’s export) and PE4 must import 101:101 (PE1’s export). No export chan

Explanation
In an L3VPN, reachability between sites depends on route-target import/export alignment. PE1 exports 101:101, and PE4 exports 104:104. For the two sites to learn each other’s routes, PE1 must import 104:104 (PE4’s export) and PE4 must import 101:101 (PE1’s export). No export changes are required.
