Router R1 has a connected route for 10.1.1.0/24 off interface Fa0/0. Interface Fa0/0 has been enabled for OSPF due to a router ospf 1 and network 10.0.0.0 0.0.0.255 area 0 command.

第8题：

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.

第15题：

On Router R1, process EIGRP 1 is redistributing routes from process OSPF 2, calling route - map fred with the redistribute ospf 2 command. R1 has learned intra - area routes for 10.1.1.0/24 and 10.1.2.0/24 in part due to the Type 2 LSAs known for each subnet. The route map filters route 10.1.1.0/24 and allows 10.1.2.0/24 througH. Which of the following co mmands on router R1 list subnet 10.1.1.0/24?（）

• A、show ip route
• B、show ip eigrp topology
• C、show ip ospf topology
• D、show ip eigrp topology 10.1.1.0/24
