Enterprise Router R1, in ASN 1, connects to ISP Router I1, ASN 2, using eBGP. There are two 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
