R1 is currently advertising prefixes 1.0.0.0/8, 2.0.0.0/8, and 3.0.0.0/8 over its eBGP connection to neighbor 2.2.2.2 (R2). An engineer configures a prefix list (fred) on R1 that permits only 2.0.0.0/8 and then enables the filter with the neighbor R2 prefix- list fred out command. Upon exiting configuration mode, the engineer uses some show commands on R1, but no other commands.
Which of the following is true in this case?（）
A. The show ip bgp neighbor 2 .2.2.2 received -routes command lists the three original prefixes.
B. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists the three original prefixes.
C. The show ip bgp neighbor 2.2.2.2 routes command lists the three original prefixes.
D. T he show ip bgp neighbor 2.2.2.2 routes command lists only 2.0.0.0/8.
E. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists only 2.0.0.0/8.
A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with Routers I1 and I2 used at th e ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1. R1 and R2 do not share a common subnet, relying on other routers internal to the Enterprise for IP connectivity between the two routers.
Which of the following could be used to prevent potential routing loops in this design?（）
A. Using an iBGP mesh inside the Enterprise core
B. Configuring default routes in the Enterprise pointing to both R1 and R2
C. Redistributing BGP routes into the Enterprise IGP
D. Tunneling the packets for the i BGP connection between R1 and R2
A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with Routers I1 and I2 used at the ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1.
Assuming as many default s ettings as possible are used on all four routers, which of the following is true about the next - hop IP address for routes R1 learns over its iBGP connection to R2?（）
A. The next hop is I2's BGP RID
B. The next hop is I2's IP address used on the R2 - I2 neigh bor relationship
C. The next hop is R2's BGP RID
D. The next hop is R2's IP address used on the R1 - R2 neighbor relationship
