A. Assuming that the RTE advertises the route 10.1.1.0, the RTD will see that the AS-PATH attribute of the route is ( 65002 ) 100 .

B. Execute displabgp peer on RTA, you can see that RTB is an IBGP neighbor, and RTC is an EBGP neighbor.

C. Compared with the reflector, a disadvantage of confederation is that all routers must support confederation, so RTB and RTD must be configured with confederation id and confederation peer-as and other related commands.

D. Execute the bgp 65002 command on RTA to start the BGP process, and execute displabgp peer on RTE, you should see the EBGP neighbor RTA belonging to AS65002

A. RTD

B. RTE

C. RTA

D. RTC

E. RTB

A. RIP-2

B. BGP

C. OSPF

D. RIP-1

A. When applying BGP manual aggregation, you can use the origin-polic parameter to change the origin attribute of the aggregated route for more flexible control.

B. BGP manual aggregation can advertise aggregated routes and specific routes at the same time, or only select specific routes to generate aggregated routes.

C. There are two types of BGP aggregation: automatic aggregation and manual aggregation.

D. Since BGP supports CIDR, BGP auto-aggregation can automatically aggregate the routes existing in the routing table into routes with natural masks

A. Intra-Area-Prefix LSA

B. AS-external LSA

C. Link LSA

D. Router LSA

E. Network-LSA

F. Inter-Area-Prefix LSA
