An Enterprise rou ter, Ent1, displays the following excerpt from the show ip bgp command.

o parallel serial links between the two rou ters. The implementation plan calls for each router to base their BGP TCP connection on their respective loopback1 interfaces, with IP addresses 1.1.1.1 and 2.2.2.2, respectively.Which of the following commands would not be part of a working eBGP confi guration on Router R1？（）

A. router bgp 1

B. neighbor 2.2.2.2 remote- as 2

C. neighbor 2.2.2.2 update - source loopback1

D. neighbor 2.2.2.2 multihop 2

us two ABRs, ABR1, and ABR2, all in area 100. The branches connect to the ABRs using Frame Relay point - to - point subinterfaces. The verification plan lists the output of the show i p ospf database summary 10.100.0.0 command on a router B1, one of the branches.Which of the following is true regarding the output that could be listed for this command？（）

A. The output lists nothing unless 10.100.0.0 has been configured as a summary rou te using the area range command.

B. If 10.100.0.0 is a subnet in area 0, the output lists one Type 3 LSA, specifically the LSA with the lower metric when comparing ABR1‘s and ABR2‘s LSA for 10.100.0.0.

C. If 10.100.0.0 is a subnet in area 0, the output lists two Type 3 LSAs, one each created by BR1 and ABR2.

D. None, because the Type 3 LSAs would exist only in the ABR‘s LSDBs.
