Which of the description about IBGP neighbors and EBGP neighbors is wrong?

- B . If two peers exchanging BGP packets belong to the same autonomous system, then these two peers are IBGP peers

Which of the following descriptions about setting Community through routing policies to affect routing selection is wrong?
- A . It can be indirectly affected. By setting the Community attribute of the route, the route can be classified, and then set different route selection-related attributes according to the category, such as Local_Pre, MED, etc., to achieve the purpose of affecting route selection
- B . It cannot be affected, because the Community attribute of the route is a non-transitional attribute and cannot be passed between routers
- C . It can be affected indirectly. By setting the Community attribute of the route, the route can be classified, and then different attributes related to route selection can be set according to the category. These attributes only include Loacal_Pre and MED, so as to achieve the purpose of affecting route selection
- D . After the router receives the routing update whose Commmity attribute is No_ Advertise, it will not advertise it outside the local AS.
