Router R1 lists 4 routes for subnet 10.1.1.0/24 in the output of the show ip eigrp topology all - links command. The variance 200 command is configured, but no other related commands are configured. Which of the following rules are true regarding R1's decision of what r outes to add to the IP routing table? Note that RD refers to reported distance and FD to feasible distanc E.()
A

Adds all routes for which the metric is <= 200 * the best metric among all routes

B

Adds all routes because of the ridiculously high variance setting

C

Adds all successor and feasible successor routes

D

Adds all successor and feasible successor routes for which the metric is<=200 * the best metric among all routes

第1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 and10.1.2.0/24 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


参考答案:A, C

第2题:

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. R1 also has EIGRP configured, with the redistribute ospf 1 metric 1000 100 10 1 1500 command configured under EIGRP.Which one of the following is true?()

A. R1 will not redistribute 10.1.1.0/24 into EIGRP, because R1 knows it as a connected route and not as an OSPF route.

B. For any OS PF routes redistributed into EIGRP, the metric components includea value equivalent to 1 Mbps of bandwidth.

C. For any OSPF routes redistributed into EIGRP, the metric components include a value equivalent to 100 microseconds of delay.

D. No subnets of network 10.0.0.0 will be redistributed due to the omission of the subnets parameter.
