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

An Enterprise rou ter, Ent1, displays the following excerpt from the show ip bgp command. ENT1 has an eBGP connection to an ISP router with address 3.3.3.3 and an iBGP connection to a router with address 4.4.4.4. Which of the following is most likely to be true?（） Network Next Hop Metric LocPrf Weight Path *> 3.3.3.3 0 0 1 1 1 1 2 18 i

• A、The Enterprise likely uses ASN 1.
• B、The neighboring ISP likely uses ASN 1.
• C、The route has been advertised through ASN 1 multiple times.
• D、Router Ent1 will add another ASN to the  AS_Path before advertising this route to its iBGP peer (4.4.4.4).

A network administrator is troubleshooing an EIGRP problem on a router and needs to confirm the IP addresses of the devices with which the router has established adjacency.

• A、Router# show ip eigrp adjacency
• B、Router# show ip eigrp topology
• C、Router# show ip eigrp interfaces
• D、Router# show ip eigrp neighbors

第18题：

A router has EIGRP configured as the only routing protocol. How does EIGRP respond if there is no feasible successor route to a destination network and the successor route fails?（）

• A、It immediately sends its entire routing table to its neighbors.
• B、EIGRP sends a Hello packet to the DR to inform it of the route failure.
• C、It automatically forwards traffic to a fallback default route until a successor route is found.
• D、It sends queries out to neighbors until a new successor route is found.
• E、It places the route in holddown until LSA updates inform it of a new route to the network.
