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?（）

第2题：
Refer to the exhibit. Routers R1 and R2 have established a neighbor relationship and are exchanging routing information.

A. R1(config)# router eigrp 1 R1(config - router)# passive - interface serial 0
B. R1(config)# access - list 2 0 deny any R1(config)# router eigrp 1 R1(config - router)# distribute - list 20 out serial 0
C. R2(config)# access - list 20 permit any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 in serial 0
D. R1(config)# access - list 20 permit any R 1(config)# router eigrp 1 R1(config - router)# distribute - list 20 in serial 0
