The following description of BGP load sharing is wrong with? (Multiple choice question)

• A.The destination CIDR blocks are the same, and load sharing can be formed between BGP routes with different sources.
• B.IBGP routes and EBGP routes that reach the same destination in the public network can form a load sharing
• C.If BGP load sharing is implemented, the local device needs to configure the peer next-hop-local command to change the next hop address to its own address when issuing a route to an IBGP peer group.
• D.The AS_Path properties of the equivalent routes that form load sharing must be different.

In the following topology diagram,

R1 can be established between R2 and R3 fetches the Internet, RI and R2, R1 and R3 EGP connections, R2, R3 belong to the same AS. The default routes are issued through BGP separately, requiring R2 to be preferred for traffic accessed by RI to the Internet, and the following practices can be achieved

• A.R1 specifies that peer R3 sets the MED property to 150 in the import direction
• B.R2 specifies peer R1 in the export direction setting MED property to 150
• C.R2 specifies that peer R1 is in export. The direction setting local priority is 150
• D.R1 specifies the peer R2 sets the local priority in the import direction to 150
