A network includes a RIPv2 domain, an EIGRP domain, and an OSPF domain. Each pair of routing domains has multiple routers redistributing routes between the p air of domains. The design requires that the redistribution configuration avoid matching based on prefix/length because of the trouble in maintaining such configurations.
Which one of the following tools can be used in all three routing domains to attem pt to prevent domain loops?（）
A. Setting route tags
B. Setting the default administrative distance differently for internal and external routes
C. Setting administrative distance differently per route
D. Setting metrics much higher for all ext ernal routes than for all internal routes

Router R1 is redistributing between two OSPF processes. Given the configuration shown, which includes all commands in the route map named fred, which of the following answers is true regarding the redistribution into OSPF process 1?（）
router ospf 1
redistribute ospf 2 external 2 route - map fred
!
route - map fred permit 10

A. No routes are redistributed because a route cannot be both E1 and E2.
B. Only OSPF E2 routes in the OSPF 2 domain will be considered for redistribution.
C. Inside the OSPF 2 domain, any formerly E2 routes will become E1 routes.
D. Routes permitted by ACL 1 will be redistributed, regardless of whether the routes are E1 or E2 routes.
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
Router R1 refers to route - map fred when redistributing from EIGRP into OSPF. The entire route - map is listed next. Which of the following answers must be true based on the configuration as shown?（）

route - map fred deny 20
match ip address two
route - map fred permit 100
A. The third route map clause will allow any routes not already filtered by the first two clauses
B. R outes permitted by ACL "two" will be redistributed
C. Routes denied by ACL "one" will be redistributed

Router R1 has been configured with the redistribute ospf 1 route - map fred command under router eigrp 1. The route map named fred needs to be configured to match routes to d etermine which routes are redistributed into EIGRP.

A. Subnet number
B. Next - hop router IP address of the route
C. Whether the route is an E1 or E2 route
D. The ro ute's tag

Router R1 sits inside OSPF area 1. Router R2 redistributes an E1 route into OSPF for prefix 2.2.2.0/24, with external metric 20. Router R22 redistributes an E2 route for the same prefix/length, external metric 10.
Under what conditions will R1 choose as it s best route the route through R22?（）
A. R1 will always choose the route through R22.
B. As long as R1's best internal OSPF cost to reach R22 is less than 10.
C. As long as R1's best internal OSPF cost to reach R22 is less than 20.
D. R1 will never choo se the route through R22 if the E1 route through R2 is available.

A. Let the metrics default.
B. Use each redistributed route's OSPF metric using the redistribute command's metric transparent keywords.
C. Set the metric using the default - metric router subcommand.
D. Redistribution is not allowed between two OSPF p rocesses.
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.
